Research on Calculation of Overall Anti-sliding Stability of Embankment on Soft Soil Foundation
Aiming at the problem of the value of the shear strength index of silty soft soil in the current stability calculation of soft foundation levee,according to the"Code for Design of Levee Engineering"(GB 50286-2013)and relying on a soft foundation levee project,This paper analyzes the influence of various factors on the safety coefficient of the soft foundation embankment from the aspects of the soil shear strength index(i.e.,fast shear strength index,cross plate in-situ shear strength)and the calculation method of the overall anti-sliding stability(i.e.,Swedish arc method and simplified Bishop method).It is concluded that the stability safety coefficient calculated using the shear strength index suggested by geological engineers is the smallest.The stability safety factor calculated by the shear strength value of the cross plate is slightly larger.The section of the stable safety system that does not meet the requirements of the code is reinforced by reducing the dredging amount,which provides a reference for similar soft foundation dike engineering design.
