摘要

Based on a practical engineering project (in Inner Mongolia), which uses composite foundation with CFG & gravel piles to deal with the soil liquefaction, the composite foundation's capacity and function mechanism are analyzed in the paper. And the design, construction effect and test results of the composite foundation are also discussed. The test results presented in the paper can be applied to the similar projects in the region of Inner Mongolia. These include the experimental parameters of the composite foundation, the test results of the carrying capacity of single pile vertical static load and heavy dynamic touch test, the test results of the pile's quality affected by low stain dynamic test and the test results of standard penetration experiment. The following conclusions can be reached from the analysis of the test results mentioned above:(1) That the engineering project involved in the paper has gotten good reinforcement effect shows that the application of the composite foundation to resisting soil liquefaction is successful, which sets an example for widely application of the composite foundation with CFG and gravel piles to treating the soil liquefaction of foundations; (2) The composite foundation with CFG and gravel piles has the functions of quickening up the soil's drainage and consolidation; and (3) During the construction of the composite foundation, the dynamical load and the shock absorption function of the piles can increase soil's density, and thereby abate or clear up soil liquefaction.
