摘要
根据高填方软土路基在超载预压情况下工后沉降变形的非线性和不确定性的特点,该文基于GEO5岩土设计软件在模拟土体固结沉降方面的准确性,并以武汉某快速公路K12+700测点作为研究目标,通过模拟该测点路基断面的土层固结沉降过程,分析高填方软土路基沉降的特点,并且验证对堆载预压工艺调整的合理性。
According to the characteristics of non-linearity and uncertainty of post-construction settlement and deformation of high fill soft soil subgrade under overload preloading,based on the accuracy of GEO5 geotechnical design software in simulating consolidation settlement of soil,taking K12+700 survey point of a Expressway in Wuhan as the research target,by simulating the consolidation and settlement process of the subgrade section at this measuring point,the settlement characteristics of high fill soft soil subgrade were analyzed,and the rationality of the adjustment of surcharge preloading technology was verified.
