摘要： 近年来塑料排水板处理在深厚软土地基海堤工程中得到了广泛的应用，通过宁波北仑七姓涂海堤基础处理的原位测试研究，分析了塑料排水板对加快软土地基固结的处理效果。表明：原位监测测试是软土海堤建设基础处理效果的检验手段，表面浮泥会在初期影响地基的整体沉降量，排水板处理软土海堤基础效果良好，大大提高了施工效率。

Abstract: The Prefabricated Vertical Drains (PVD) have received a wider application in improving thick soft soils in sea dike projects in Ningbo area. This paper presents the results of improving the thick soft soils in the Beilun Qixin Coastal Sea Dike Project. The results indicate that the insitu testing is an effective tool for the soft soil strengthening projects. The clay debris at the ground surface would affect the initial settlement of the improved soils. The PVD is an effective and efficient tool for the sea dike soil improvement.
