| 摘 要： | 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。

| Abstract: | It is very important to determine the bearing capacity of foundation,which is a key point for designing composite foundation.Pipe pile and mixing pile composite grounds are employed to consolidate soft base.Earth pressure cell is embedded on the two consolidation areas to study the law of earth pressure.Then the bearing capacity transferability of composite ground is deeply analyzed and appropriate pile-soil stress ratio is recommended.This research not only helps to understand the property of bearing capacity transferability but also guides the construction of composite ground. |

| Keywords: | road engineering composite foundation bearing capacity of composite ground pile-soil stress ratio |
