摘要
介绍在国内首次采用土工格栅建造的柔性加筋土挡墙处理在软基上填筑加高帮宽路的工程实践 ,以及设计计算 ,并阐述筋材和土体协调变形等问题。变形的主要原因是差异沉降对既有路堤的影响 ,采用传统的方法易留下工程的隐患。工程实践证明 ,采用柔性加筋土挡墙在软基上解决此类问题是成功的 ,且操作简便易行 ,并可降低工程造价 。
This paper presents the application of geogrid reinforced retaining wall plus high embankment in soft ground treatment, for the first time in China, including design and calculation of the reinforcing materials and the earth block coordination and deformation. It is found that the main cause of the deformation is the impact of differential settlement on the existing embankment, therefore the traditional treatment methods usually have hidden risk. The practical engineering practice shows that the application of the flexible reinforced retaining wall in the soft ground treatment has been successful, which is easy to implement and cost effective.
