对于复合地基来说,地基承载力的确定至关重要,它是设计复合地基时必须考虑的一个重要因素。研究采用了搅拌桩复合地基及管桩复合地基进行软基加固处理,通过在这两个加固区设置静土压力盒来掌握桩土压力的变化情况,进而分析复合地基承载力的传递性状,并推荐了合适的桩土应力比数值。这不论是对复合地基承载力传递性状的分析研究,还是对工程实践,都是非常有意义的。
For the composite foundation, the determination of the bearing capacity of the foundation is very important. It is an important factor that must be considered when designing the composite foundation. The study uses the mixing pile composite foundation and the pipe pile composite foundation to reinforce the soft foundation, and sets up the earth pressure box to grasp the change of the pile-soil pressure in these two reinforcement zones, and then analyzes the transfer characteristics of the bearing capacity of the composite foundation Recommended a suitable pile-soil stress ratio value. This is very meaningful whether it is the analysis of the bearing capacity transfer of composite foundation or the engineering practice.
