摘要
道路修建在软土地基时,需要对其进行处理。软土地基处理方法较多,处理方法合理则会使得地基承载力提高,地基沉降量减小,工程成本节约。主要分析了超载预压法、换填法、强夯法、复合地基法及土工合成材料法处理软土地基的工作原理及其适用性分析,最后,提出了软土地基沉降的预测方法。
Roads need to be constructed in soft soil areas.There are many soft soil foundation treatment methods,and reasonable treatment methods can not only improve the foundation bearing capacity,reduce foundation settlement,but also save engineering costs.This paper mainly analyzes the working principle and applicability analysis of soft soil foundation treated by overload preloading method,replacement filling method,dynamic compaction method,composite foundation method and geosynthetic method.Finally,the soft soil foundation settlement prediction method is proposed.
