摘要

水泥搅拌桩加固有机质含量较高和呈酸性的土层时

我国规范建议采用现场试验的方法。通过深层搅拌法加固太湖应天河工程富含有机质的淤泥质酸性土地基的多组现场水泥土强度试验

分析了淤泥质酸性土中影响水泥土强度的各种因素。试验和工程实践表明

使用高标号水泥（525#）并掺入适量的外加剂可大幅提高酸性淤泥水泥土的强度

复合地基承载力可达120kPa以上

水泥搅拌桩可以加固淤泥质酸性土地基。

Abstract

Testing method is adopted in the codes when the foundation in mucky-acid soil is stabilized by cememt deep mixing method. Based on the test of cement-soil strength test for Yingtian River Project by deep cement mixing method

this paper analyzed the influencing factors of cement-soil strength and took improved measures to solve it. The test results and practice show that the cement-soil strength is increased by high grade cement and admixture.
