This calculation is performed by applying the non-linear failure criteria of the Focus Procedure of Úcar and Hoek–Brown’s and implementing the necessary formulae in a spreadsheet. The aim is to provide a simple, cost-effective, and easy-to-use procedure that is useful in the early stages of a project or as a starting point for more detailed investigations. Besides slope geometry and strength parameters, the required parameters are the RMR of the rock mass or its m i , depending on the criterion used. The proposed procedure allows for the estimation of the factor of safety, the position and depth of the tensile crack, and the inclination of the failure plane in the most unfavorable case, with reasonable accuracy, using an iterative process with the conventional tools available in common spreadsheet programs. An example is provided in which an accuracy of 86–96% for the factor of safety is obtained.","PeriodicalId":48246,"journal":{"name":"Geotechnical and Geological Engineering","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135259538","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}

Basement construction is an unavoidable problem in urban areas. A case is found in a Triumph Unit building block project, where a 14 m basement will be constructed near the existing structures. Conducting a site survey engineering analysis before the deep basement excavation is essential to guarantee safety during basement construction. Site survey engineering analysis is vital in recommending a suitable support structure for the basement pit during excavation. Therefore, this paper takes the Triumph Unit high-rise building basement excavation project as a practical application of site survey engineering analysis on the actual construction site. Geotechnical and groundwater characterisation were achieved through field and laboratory tests. The study revealed that the site was suitable for construction of bored piles as enclosure structure. It also recommended application of steel bracing material enhanced with a hydraulic servo system as basement excavation internal support structure. The recommended support structure is applied to the actual excavation. The excavation-induced deformation with respect to the recommended support structure application is strictly monitored and controlled. The measured project site results show the effectiveness of site survey engineering analysis in recommending a suitable deep basement excavation support system that controls the excavation-induced deformation desirably.","PeriodicalId":48246,"journal":{"name":"Geotechnical and Geological Engineering","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135397415","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}
