NUMERICAL INVESTIGATION ON LATERAL MOVEMENTS OF A COMPOUND DEEP CEMENT MIXING WALL
Keywords:
Deep mixing, excavation, parametric study, simulation, soil stabilizationAbstract
This paper presents parameters affecting the lateral movement of a compound deep cement mixing retaining wall using the three-dimensional finite element method. A numerical model is first calibrated with an instrusmented case history. Then, a parametric study is performed. The influences of various parameters are compared and rated in terms of the degree of importance. The numerical results show that the thickness of the soft clay, the modulus of elasticity of the deep cement mixing column, and the nonexistence of the stabilized mat are the 3 most important design parameters.
