| 摘 要： | 通过采用塑料排水板超载预压处理高速公路软土地基4年多的现场试验，对路堤填筑及预压过程中的地表沉降、横向差异沉降、深层沉降、孔隙水压力及深层水平位移进行了分析．采用塑料排水板超载预压处理高速公路软土地基，具有较好的效果，不仅使沉降大部分在填筑期和超载预压期间发生，且使卸载后再施工路面结构层时沉降速率仍然呈收敛的状态．在软土地基上修建路堤时，建议开展动态设计．后期横向差异沉降基本不会对通车产生不利的影响．超载卸载再加荷后，深层水平位移基本不增加．

| Abstract: | The soft soil foundation was treated with plastic drainage belt in combination with surcharge. Its behaviors were studied including settlement, pore water pressure, and deep horizontal displacement. Good effect was gained on the soft foundation treated with plastic drainage belt in combination with surcharge. The final settlement accomplished mostly during the period of filling and surcharge preloading. The velocity of settlement decreased during reloading period following the primary unloading. Control design should be applied in the construction of soft soil embankment. Landscape orientation differential settlement did no harm to traffic. Deep horizontal displacement scarcely increased after unloading and reloading. |
