水泥土搅拌桩在海堤淤泥质地基加固中的应用

水泥土搅拌桩加固地基技术具有施工速度快、基础最终沉降量小、施工时无振动、低噪声和对周围建筑无有害影响等优点，在一般建筑物软基处理中应用广泛，但在海堤淤泥质地基处理中应用的实例较少。深圳西海堤加高加固工程，海堤地基为淤泥，且厚度深，工期受度汛限制要求紧，地基加固经多方案比选后采用了水泥土搅拌桩．达到r较好的工程效果。工程实践表明．该技术也非常适合在淤泥质海滩上对已有海堤加高加固工程的地基进行处理。

Application of Cement & Soil Stirring Pile in Strengthening the Silty Foundation on Seashore Levee

The technique of strengthening foundation with cement & soil stirring pile can speed up the construction, lessen the sinking of the foundation, less vibration, low unpleasant noise during construction and no bad impacts on the nearby buildings. It is extensively used in process-ing common buildings on soft-foundation. However, there are few examples to use it in dealing with the silty foundation on seashore levee. In the project of heightening & strengthening in Shenzhen western seashore levee, according to the facts of the thick silt and the urgent working time confined by the flood season, finally adopted the technique after detailed contrasting. It achieved better construction effect. It is proved that the technique is very suitable to deal with the silty foundation in seashore levee heightening & strengthening project by the case.
