摘要
深层搅拌桩用于软土地基的处理而与桩间土组成复合地基，在我国软土地区得到广泛且成功的应用．但实际工程应用中也暴露出一些问题，并影响其应用前景．为此，本文深入地进行了深层搅拌桩的室内实验、现场测试及复合地基现场测试的研究．
The MIP composite foundation, composed of .mixing in place piles and soil between pilos,comns into vast and sucessful use in thc soft soil regions of China. But some problems appear in actual engineering. This paper proscnts our research on MIP composite foundation by means of experiments in laboratory and-the-spot tests.
