摘　　要：文章根据淮盐高速公路淮安三合同段软基特点并结合室内试验结果对高含水量条件下水泥土强度特性进行了研究,结果表明软土含水量对水泥土强度和成桩质量有明显影响,软土含水量低于80％时水泥土强度与含水量成正比,超过80％时水泥土强度会明显降低。增加水泥用量可明显提高水泥土强度,使用外加剂可有效改善水泥土性能。The strength characteristic of cement - soil under the condition of high water content is studied in the paper by means of laboratory test according to the characteristic of soft clay foundation in NO. 3 part of Huai' an in Huai - Yan Expressway. It shows that water content has an important influence on the strength of cement - soil and pile quality. The strength of cement -soil will be increased with the accretion of water content if the water content is lower than 80% while the strength of cement -soil will be decreased obviously if the water content is higher than 80% . The strength of cement - soil is improved with the accretion of cement and so does the admixture.
