Finite-element analysis of deep excavation in layered sandy and clayey soil deposits

摘要: This paper presents an application of finite-element analysis to deep excavation in layered sandy and clayey soil deposits using a combination the hyperbolic Modified Cam-clay models. In analysis, drained behavior cohesionless undrained cohesive were simulated models, respectively. A rational procedure for determining parameters each models was established. simulation dewatering process during proposed. The analytical confirmed through three actual cases. Finally, analyses considering pore-water pressure dissipation elapsed time construction phase carried out. results indicate that calculated displacement retaining wall is smaller than given by analysis. It thought some degree actually occurs intermedia...
