CFG复合地基静载荷试验研究

Study on Static Load Test for CFG Composite Foundation

以呼和浩特绕城高速公路碎石桩复合地基为工程依托,通过静载荷试验,对碎石桩处理前后地基承载力,以及复合地基桩土应力比进行现场测试和分析,并对间接法和直接法确定复合地基承载力的结果进行比较,得出一些有益的结论,为实际工程提供了理论和现场实测依据。

Based on the project of gravel pile composite foundation for Round - town Expressway in Hohhot city, on site test and analysis have been made to the capacity of gravel pile foundation before and after treatment as well as pile - soil stress ratio of composite foundation. After comparison of the results of direct test and indirect test for bearing capacity of composite foundation, some beneficial conclusions are obtained which has provided theoretical and on site test basis to actual project.
