摘　　要：在水泥粉喷桩单桩、复合地基以及天然地基载荷试验的基础上 ,阐述了桩身应力应变随深度呈非线性分布、桩土应力分担比随荷载而变化、复合地基与天然地基载荷板下应力分布以及复合地基与天然地基承载力等的试验结果 。Based on the static test of DJM pile, composite foundation and natural foundation, authors analyze the test results of non linear distribution of stress and strain that vary with depth of pile,stress ratio between pile and soil,distribution of stress under bearing plate of composite and nature foundation, and bearing capacity of composite and nature foundation.It points out that delivery depth of stress and strain in pile is finite.
