淤泥就地固化技术在公路路基中的应用实例

In-situ Solidification of Soft Mucky Cohesive Soils for a Highway Subgrade

针对平原水网地区公路穿越河塘暗浜问题,采用淤泥就地固化技术代替传统清淤换填方法加以处理,具有经济环保实用优势。在介绍淤泥就地固化施工设计技术的基础上,结合工程应用实例,分析该类浅层地基处理技术的适用性和加固效果,为类似工程提供借鉴和参考。

This paper introduces a cost effective and environmental friendly in-situ solidification of soft mucky cohesive soil technique that replacing the conventional soil improvement method of removal and replacement for a highway project in an alluvial plain with well-developed rivers and creeks and hidden historical waterways.The construction techniques of the in-situ soft mucky cohesive soil are also briefly introduced and a case history of the project that applying this soil improvement method is presented in this paper.Further,the applicability as well as results of using this technique for strengthening of shallow deposited soft cohesive soils are evaluated.
