软土在我国山谷地、湖盆地周围及平原沙口三角洲均有广泛分部。在工程实践中经常会遇到在软土地基上修筑路基问题,若处理不当会发生路基失稳或过量沉陷而导致公路非正常状态使用,2005年5月12日发生在萧甬铁路段的软土流陷事故即比较典型。本文从投资少、效益高、安全实用及少占农田原则出发列出了筒明实用的九种软土地基处治方法,为建筑设计、工程施工单位及工程类院校提供了作业指导及教学参考。
Soft soil in China’s valleys, lake basins and plains have a wide range of sub-Shakou. In engineering practice, it often encounters the problem of building subgrade on soft soil foundation. If it is not handled properly, subgrade instability or excessive settlement will lead to abnormal use of the highway. On May 12, 2005, the soft subgrade Soil erosion accidents are more typical. Based on the principle of less investment, high efficiency, safety and practicality and less occupation of farmland, this paper lists nine practical methods of soft soil foundation treatment, and provides guidance and teaching reference for architectural design, construction units and engineering colleges .
