In order to control the large deformation in the process of tunnel construction, the advanced drilling measure and the advanced pilot tunnel measure are proposed and relevant field tests are carried out to verify their results. Compared with conventional support measure, the advanced pilot tunnel measure has better control effect on horizontal convergence and vault settlement, which are reduced by 29.70% and 75.81% respectively. What's more, the advanced drilling measures has more advantages in the control of the maximum of surrounding rock stress and the maximum of steel frame stress, which are reduced by 77.44% and 23.12% respectively. The results show that the large deformation of strongly weathered carbonaceous slate tunnel in high geostress cannot be effectively solved by the conventional support measure, but the two advanced stress control measures can effectively reduce the deformation of the surrounding rock of the tunnel, and decrease the stress of the tunnel steel frame and surrounding rock.","PeriodicalId":49670,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Transport","volume":"25 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83399820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite technological progress, high amounts of resources are still wasted worldwide due to the wrong usage of energy systems in existing building stock. As a response, this paper proposes a recommendation system that is based on information and communication technologies and that provides building users with hands-on executable recommendations to reduce their energy consumption. Indeed, because of their lack of energy awareness and knowledge, people may need guidance in their daily usage of a building to change their energy behaviour and to save energy. For that purpose, the recommendation system analyses building operation data in real time to identify energy wastes as well as suitable energy conservation measures that shall help in saving energy. One main challenge is to provide a highly scalable solution that can be easily applied in a wider range of buildings, thus enabling resource saving at a large scale or even worldwide. For that purpose, the system relies on a model-based expert system for easy adaptation in any building regardless of its type, size and usage.","PeriodicalId":49670,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Transport","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136132074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the approximation models of objective function and constraints are established based on the radial basis function and the intergeneration projection genetic algorithm is applied to find the optimal solution. According to the error evaluation of optimal solution, secondly, the function fluctuation index is used to adopt the local sample points. Meanwhile, the global sample points are solved by the inherited Latin hypercube design to ensure the distribution uniformity of samples in the whole design space. Furthermore, the weighted Euclidean distance criterion is performed to evaluate the rationality between the samples. Then, the qualified samples are added to the sample space to update the approximation models of the transportation equipment. Based on the above multi-criteria sample updating and management strategy, the more accurate optimisation results could be obtained. Finally, the effectiveness of the method and the applicability in practical application of transportation equipment are investigated by one numerical test and one engineering example.","PeriodicalId":49670,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Transport","volume":"35 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81347803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As these tests have a long execution time and high cost, this study analysed the variation of the Resilient Modulus (using composite model tested and linear predicted values) of the low-volume road subgrade and the impact on the pavement design. This study simulated four different subgrades considering the soils of the Metropolitan Region of Fortaleza, Ceara, Northeastern Brazil and three predefined pavement structures. Total and subgrade rutting provided by the MeDiNa software was used as an evaluation parameter. The simulation results allowed the authors to verify that the calculated rutting values are very close despite the Resilient Modulus adopted. In conclusion, road designers can consider any predicted linear value of the Resilient Modulus or the composite models in the design of these highways, even with forecast errors greater than 20%. The study also proposes a low-volume road design catalogue considering the subgrades analysed.","PeriodicalId":49670,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Transport","volume":"103 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85858366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
