The gravel piles with vibroflotation are used to treat the soft soil and liquefaction of saturated silt of a proposed power plant project,and many field test studies are carried out. After finishing the construction of the testing piles,a lot of in-situ tests including plate loading test,stand-ard penetration test,lab test,ultra-heavy dynamic penetration test,etc. are used to evaluate the bearing capacity of soil between piles,piles and composite foundation,to test the deformation parameters,and to evaluate the controlling effects of liquefaction. A large number of reliable experi-mental data are obtained,which are valuable for similar projects.%某拟建电厂工程通过采用振冲碎石桩复合地基的处理方法，开展了软弱液化地基治理的现场试验研究，试桩施工结束后，采用载荷试验、标准贯入试验、土工试验、超重型动力触探试验等原位测试方法，对桩间土、桩体及复合地基的承载性能、变形参数及液化处理效果进行了评价和分析，取得了大量可靠的试验数据，对类似工程具有一定的参考价值。
