水泥土搅拌桩复合地基室内模拟试验研究

通过水泥土搅拌桩的室内模拟试验，得出了水泥土搅拌桩桩身刚度、持力层刚度、有效桩长之间的关系．本室内静载试验模型虽然不能完全模拟现场水泥土搅拌桩的破坏状态，但从定性上分析水泥土搅拌桩复合地基的工作机理是可行的．由于本试验模型操作方便，省时省力，能实现多种试验功能，可以予以推广；又由于此模型试验结果与现场试验结果的一致性，对水泥土搅拌桩的实际工程设计，具有一定的参考价值。

Study of Indoors Imitating Experiment of Cement- Soil Mixing Piles

By indoors imitating experiment of cement-soil deep mixing piles,the author of this article infers the relationship between cement-soil stength,staying power,layor strength and effective pile length.Although the indoors experiment model can't imitate the state of destroying in testing ground completely,it is feasible in qualitative analysis of the working mechanism of cement-soil mixing piles.Because the model is easy to operate,time-saving,power-saving,it can be used widely in the future.What's more,the result of model experiment is in agreement with that of testing ground.So it is useful to the design of cement-soil mixing pile in real engineering project.
