Optimization of supporting schemes for deep foundation pit based on Delphi method and precedence diagram method
摘要
Abstract
A good deep foundation pit support scheme can ensure project safety to a large extent while saving construction costs.By combining the Delphi method and the precedence diagram method,the existing deep foundation pit support scheme is optimized,and the optimized support scheme is simulated by Abaqus finite element software.By Delphi correspondence method,several experts familiar with the situation in the project area evaluate the relative importance of the influencing factors in the excavation process of the deep foundation pit,and the scores of these influencing factors in the scheme are obtained.And weight analysis is carried out by precedence diagram method,and the relative optimal scheme is selected from the existing deep foundation pit support scheme.The model is established by combining Abaqus finite element software to simulate the engineering examples and compare with the actual situation.It shows that the Delphi method combined with precedence diagram method is scientific and practical with good reliability.关键词
