Abstract:
Through the model test, bearing capacity test in-situ of soil-cement mixing pile and cast-in-place pile and finite-element method, the load transfer and failure mechanism of the soil-cement mixing pile is studied. The loading plate-pile-soil interaction of the loading plate test of soil-cement mixing pile composite is also studied. The effect of the cushion on the bearing capacity of soil-cement mixing pile composite is analyzed and the results show that the cushion can not be simply regarded as favorable to enhance the bearing capacity and reduce the settlement of soil-cement mixing pile composite. Finally, the method to evaluate the bearing capacity of soil-cement mixing pile and its mode of failure is suggested.
