水载预压在软土路基处理中的应用浅析

Application of water preloading in soft soil subgrade treatment

现阶段,软土地区地基处理主要采用土石方堆载预压的方法,但是受土石方短缺的影响,软土地区路堤堆载预压成本不断上升。在水资源丰富的沿海平原地区,水载预压是一种成本低、工期短、环保效应好的处理方法。基于水载预压在国内的应用现状,总结了该方法的施工要点、优缺点及发展趋势,为相关工程提供参考。

Currently,the foundation treatment in soft soil areas mainly adopts the method of earthwork preloading.However,due to the shortage of earthwork,the cost of the subgrade surcharge preloading in soft soil area is increasing.In coastal plain areas with abundant water resources,water preloading is a treatment method with low cost,short construction period and good environmental protection effect.Based on the application status of water preloading in China,the construction key points,advantages,disadvantages and development trend of this method are summarized.It can provide reference for related projects.
