摘　　要：在浙江某电厂煤场大面积饱和软土地基处理中 ,采用塑料排水板堆载预压法 ,通过控制每级荷载堆煤高度和堆煤预压时间 ,使地基土在压缩变形的同时强度也逐步得到提高 ,满足了工程需要 ,取得了良好的加固效果。Prefabricated drains in combination with preloading of coal stack were used in improving the saturated soft soils in a power plant dry coal yard in Zhejiang provincial.The soil's strength were increased gradually as well as the ground's settlement and transmutation within the permitted range by controling the height and delay time of coal stack at every consolidation pressure stage.As a result,the soft soil's strength fulfilled the demand of the project.This method in treating with soft soil is satisfying.
