预应力混凝土管桩在软基道路中的应用分析

软土地基上修建道路 ,尤其是高填土路堤的软基处理方法很多 ,如 :预压、塑料排水板 +等 (超 )载预压、粉喷桩、路堤桩 +土工格栅、轻质粉煤灰路堤等等。近年来在软土深厚 ,填土较高 ,桥头路基或小构造物基础处施打预应力混凝土管桩的复合地基法处理软基 ,收到很好的效果 ,起到缩短工期 ,防止桥头土基滑移 ,避免通车早期就出现“桥头跳车”的现象 ,有利行车安全。

APPLIED ANALYSIS OF PRE-PRESSING STEEL REINFORCEDCONCRETE TUBULAR PILE IN SOFT BASE FOUNDATION ROAD

To deal with the soft base we impose the composite base method of pre-pressing steel reinforced concrete tubular piles in the places where soft soil deep and thick,higher backfill,the base of the end of a bridge or the little structural base resent years.Using this method,the result is very good,the time limit for a project is shortened,the end of a bridge is prevented to slide,the phenomenon of the end of a bridge jumping can be prevented to emerge in the early time of being open to traffic,and the safe of the transportation can be beneficial.
