摘　　要：为了解高水灰比时水泥土搅拌桩墙施工中的水泥土强度情况,通过室内无侧限抗压强度试验,对不同掺量、不同龄期下水泥土的强度特性进行了分析,并推导出了基于水泥掺量的强度预测经验公式。分析表明,相同龄期下,可由经验公式根据某一掺量的水泥土强度直接预测另一掺量时的强度,这对实际工程中的设计施工与质量控制具有积极指导意义。To understand the strength characteristics of cement-soil made churned pile wall in construction under high water-cement ratio, the unconfined compressive strength test were carried out to analyze the strength characteristic of the cement-soil in different ages and mixing amount, then the empirical formula of the compressive strength with mixing amount was ob-tained. It shows that for the same age, the strength of cement soil with a certain mixing amount can be predicted on the basis of the known strength of another mixing amount by using this experience formula.
