鉴于沿海地区饱和软粘土具有高压缩性、强度低等特点，修建公路工程中地基的沉降变形不能满足工后要求，因此必须对地基进行处理，以便满足工程需要。文中以一个塑料排水系统的堆载预压法工程实例实测资料与沉降理论公式的计算，分析两者的差异以及造成的原因，提出有益的结论供相似工程借鉴。
鑒于沿海地區飽和軟粘土具有高壓縮性、彊度低等特點，脩建公路工程中地基的沉降變形不能滿足工後要求，因此必鬚對地基進行處理，以便滿足工程需要。文中以一箇塑料排水繫統的堆載預壓法工程實例實測資料與沉降理論公式的計算，分析兩者的差異以及造成的原因，提齣有益的結論供相似工程藉鑒。

In view of the coastal areas of saturated soft clay has high compressibility, low intensity, The settlement of building foundation in highway engineering deformation can not meet the requirement of the after work, so you must to deal with foundation, in order to meet the needs of the project. This paper with a plastic drainage system stack preloading engineering examples, the measured data and subsidence theoretical formula calculation, to analyze the differences and reasons, put forward useful conclusions provide reference for the similar engineering.
