Taking soil slope as an example, this paper connects the development process of slope deformation with the stress and strain state inside the slope through finite element data simulation, finds the evolution law of slope instability failure from the change process of displacement, establishes the relationship between slope deformation monitoring data and stability. The research results show that: with the decrease of the safety factor, the displacement of measuring point increases gradually. When the slope is near failure, the displacement of measuring point increases abruptly. At the same time, the displacement of measuring point at different positions on the slope is different, the increase in displacements of measuring point in the range of sliding body is very significant, revealing the different sensitivities of slope stability development. Therefore, the sensitivity of different locations should be fully considered when arranging the monitoring points in the slope monitoring project. The results of the study provide methods and approaches for effectively evaluating slope stability; and can be used as a reference for similar projects.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 2","pages":"385-399"},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Steel support plays an active role in reducing the deformation of the enclosure structure. In order to explore the influence of pre-stress of steel support on the deformation of ground connecting wall in foundation pit engineering, this paper takes a subway foundation pit under construction in Nanjing Metro as an example by numerical simulation, and discusses the change law of ground connecting wall during excavation and the influence of steel support on the maximum deformation of ground connecting wall under different pre-stress. The analysis shows that with the increase of excavation depth, the displacement of ground connecting wall increases gradually. When the axial stress of the steel support is applied, the deformation of the enclosure structure can be effectively reduced. When the axial stress of the steel support is increased, the maximum displacement of the ground connecting wall gradually decreases, which is approximately linear.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 2","pages":"546-551"},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional driving factor identification is based on a single-factor correlation analysis, which does not reveal the mutual effect of exogenous inputs, or selecting the combination of driving factors with a trial and error method which is impractical under a lot of possible driving factors. To address these issues, this study proposes an artificial intelligence based framework. It integrates a previously calibrated hydrodynamic model that generates detention basin operation samples under different hydrological conditions and operating policies and a data-driven input variable selection algorithm that automatically selects the combination of driving factors. Take the effect of the Honghudong Detention Basin (HDB) operation on water level reduction at Hankou station in the Yangtze River basin as a case study. The results show that the detention basin operating policy is most relevant for the HDB operation effect, followed by the upstream hydrodynamic condition. This provides insights into the relevance of input variables to the detention basin operation effect and a deeper understanding of the underlying physical processes, which is meaningful for improving detention basin operation.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 2","pages":"1807-1820"},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary to study the mechanism of extreme wind-wave combined action on offshore structures especially unstable ones for their safety and performance. Utilizing the theory of random waves, this study examines irregular wave actions, focusing specifically on the maximal double-cantilever configuration of a continuous rigid frame bridge during construction. The dynamic response of the structure under extreme wind-wave combinations is analyzed, accounting for the effects of flow velocity and piles-group interactions. By comparing with the results of regular wave analysis, it was found that under the corresponding combination of load conditions, the maximum displacement effect of the structure obtained by using irregular waves was about 20% greater than that obtained by using regular waves, and the maximum internal force effect was about 10% greater. Therefore, using regular waves for structural dynamic analysis may result in smaller results and underestimate the structural responses.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 2","pages":"1542-1554"},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fiber Reinforced Polymer (FRP) offers a high-performance solution with its lightweight, corrosion-resistant, and high-strength properties, making it widely used across various fields. Similarly, Ultra High Performance Concrete (UHPC) has emerged over the past 30 years as an innovative cement-based composite with exceptional mechanical properties and durability. When compared to FRP-concrete composites, FRP-UHPC composites provide superior load-bearing capacity, reduced weight, and enhanced durability. To study the process, phenomena, and modes of damage of hybrid beams with various shear-to-span ratios and concrete conditions, four glass fibre-reinforced polymer (GFRP) profile-normal concrete hybrid beam specimens and one GFRP profile-ultrahigh-performance concrete (UHPC) hybrid beam specimen were designed and tested in four-point bending tests. The stiffness and bearing capacity of the GFRP profile-normal concrete hybrid beams gradually decreased as the shear-to-span ratio increased. The GFRP profile-UHPC hybrid beam members had better load-bearing capacity and stiffness than the fibre-reinforced polymer (FRP) profile-normal concrete hybrid beam members. When the UHPC underwent compressive damage, the hybrid beam displayed obvious ductility as opposed to the GFRP profile-normal concrete hybrid beam, which had insufficient ductility and showed no obvious evidence of damage. According to a parametric study, the ultimate load capacity of the hybrid beam declined as the shear-to-span ratio gradually rose.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 2","pages":"841-847"},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
