摘　　要：叙述了利用小应变动测法和静力触探检测深层搅拌桩的桩身质量及承载力的基本原理、工作的程序和有关成果。实践证明，这种组合方法检测桩基的思路是可行的，工程已予验证。探讨深层搅拌桩复合地基的检测方法。Forced blending with soft earth in the deep foundation,the deep mixing pile with cement as consolidation agent is a concrete pile providing certain vertical loading capacity.The composite foundation of deep mixing pile is suitable for the foundation of buildings with multiple storey brick mixing structure and light industrial factory buildings.The composite foundation is available to reduce inhomogenous subsidence and increase the bearing capacity.The paper states the basic principle of inspection for pile shaft quality,bearing capacity of deep mixing pile,operating program and results according to the dynamic inspection of small strain and static sounding method.The engineering construction shows that perfect results can be obtained applying the composite method to examine pile shaft quality and its bearing capacity.So,it is a simple method of inspection with good precision.
