公路软土地基处理设计方法探讨

对公路软土地基处理规范中的容许工后沉降存在的一些不完善情况进行了分析讨论,根据公路工程技术标准及公路运行实际情况提出公路软土地基处理设计遵循基本原则及其设计思路,分析讨论软土地基处理技术的沉降计算方法,提出公路软土地基处理的设计方法并应用于某一级公路桥头软土地基处理设计中。结果表明：用此方法进行公路软土地基处理设计能较好地过渡公路差异工后沉降。

Analysis of Design Method for Highway Soft Foundation Treatment

The faultiness of allowed post-construction settlement stated in the criterion for treatment of soft foundation under road is analyzed and discussed,the basic design principle and design consideration for treatment of soft foundation under road is put forward according to the technical standard for highway engineering and the running experience of highway,and the computing method of settlement in soft foundation treatment is discussed. The design method for treatment of soft foundation under road is put forward and used in the design work of soft foundation treatment in a first class highway engineering. The results show that unequal post-construction settlement could be controlled using this method.
