From the direct shear tests, it is observed that the angle of internal friction increases from 27.59° to 40.1° and 34.82° for copper and steel slags, respectively. The tests are done by installing the SCP in a soft clay in California Bearing Ratio mould and it is tested under soaked and unsoaked conditions. The optimum percentage found from the study for both the slag material is 30%. Tests were also done by air-curing the composite soil within the mould for 7 days and water-curing the sample under soaked conditions for 4 days for the optimum replacement percentage.","PeriodicalId":47238,"journal":{"name":"International Journal of Geotechnical Engineering","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47114595","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}

Along these lines, based on the on-site CPTU test and laboratory test results of the Huai’an-Jiangdu section of the Beijing-Shanghai high-speed expansion project, the physical and mechanical parameters of the soils were obtained in this work. In addition, by performing numerical simulations, the laws of settlement and deformation of both new and old embankments were systematically studied. From the acquired results, it was demonstrated that the deformation regularity of the whole subgrade before and after the expansion was the same, while it was observed that it only diffused outwards. However, according to the analysis of additional deformation after expansion, it was found that the load exerted on the widened part had a greater influence on the widened part of the foundation. The numerical simulation outcomes of the highway expansion foundation can provide design guidance for differential settlement control and monitoring of both the new and old highway foundation.","PeriodicalId":47238,"journal":{"name":"International Journal of Geotechnical Engineering","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46546295","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}

Results showed effective water repellency, with contact angles ranging from 119.5° to 148.5°. Larger grain size reduced contact angle while increasing surface roughness raised it. Water drop penetration time tests showed no penetration after 2 hours (7200s), regardless of grain size, with breakthrough pressure values declining with larger grain and pore sizes (2kPa - 0.1kPa). This study discusses highlights the importance of considering grain and pore size effects when using water-repellent soils in pavement construction.","PeriodicalId":47238,"journal":{"name":"International Journal of Geotechnical Engineering","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44151066","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}

This study introduces a novel test apparatus to understand micromechanical factors and deformations at grain contacts. Using a non-contact Digital Image Correlation (DIC) technique, deformations were measured with a 10 μϵ spatial resolution. This enabled quantification of grain creep and contact maturing deformations, surpassing previous experimental methods. To model this complex behaviour, Machine Learning (ML) models, including an artificial neural network (ANN) and long-short term memory neural network (LSTM), were used, achieving a 1-2% error rate with experimental results. The integration of ML offers a promising tool for predicting long-term grain strains, enhancing the assessment of structures' serviceability with the studied materials.KEYWORDS: Time-dependent behaviourageing behaviourgrain contact deformationDigital image Correlation (DIC)Machine Learning (ML) modelling AcknowledgmentsThe authors thank for the support of the conducted experimental study given by the German Federal Institute of Waterworks (Undecanal für Wasserbau, BAW), Zentrum Geotechnik of Technical University of Munich and Indian Institute of Technology Delhi.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe work was supported by the German Academic Exchange Service New Delhi [91715357].","PeriodicalId":47238,"journal":{"name":"International Journal of Geotechnical Engineering","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135895446","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}

Amith, Ganesh Kumar","doi":"10.1080/19386362.2023.2264055","DOIUrl":"https://doi.org/10.1080/19386362.2023.2264055","url":null,"abstract":"ABSTRACTRecently, occurrence of repeated shaking events such as the Kobe earthquake (1995), the Wenchuan earthquake (2008), the Chi-Chi earthquake (1999) and the Kumamoto earthquake (2016), Kahramanmaras earthquake (2023), etc., posed a severe threat to the safety of infrastructures. Studies on the influence of repeated shaking events on underground structures are minimal. Considering the above, tunnel-soil interaction under repeated shaking events is attempted in the study. One-gram shaking table tests were conducted in this study by varying loading frequency (5 Hz, 10 Hz) and tunnel embedment depth (H/W − 0.85 and 1.2 where H is the tunnel embedment depth and W is the width of the tunnel) and subjected to incremental shaking conditions, i.e. 0.2 g, 0.3 g and 0.4 g. A tunnel-embedded ground with 60% relative density was prepared and instrumented with conventional sensor schemes and a non-contact-based 2D digital image correlation technique. It was observed that the loading frequency and tunnel embedment influences tunnel’s performance during repeated shaking events. About 37% to 62.4% increment in tunnel displacement was observed in the case of H/W-0.85, and 20% to 29% increment in tunnel displacement was observed for H/W-1.2 when subjected to incremental acceleration shaking, i.e. 0.2 g to 0.4 g for varying embedment depth conditions.KEYWORDS: Tunnel-soil interactioninfluence of embedment depth of tunneluni-axial shaking table testsconventional monitoringdigital image correlation (DIC) AcknowledgmentsThe authors would like to thank the Director, CSIR-Central Building Research Institute, Roorkee, for giving permission to publish this research work.
