某路堤软基处理及监测分析

Analysis of soft soil foundation treatment and monitoring in an embankment

结合工程实例,通过理正岩土计算6.5PB2版建立计算模型,分析评价了堆载预压法处理路堤软基的加固效果。通过深层水平位移监测、边桩水平位移监测以及地表沉降监测,掌握软土地基在堆载预压时的变形规律,控制加载速率,确定预压时间,确保施工安全和工程质量,达到反馈设计、指导施工的目的。结果表明,采用堆载预压法处理路堤软基是可行的。

Based on an actual project, model is built by Lizheng software of version 6.5PB2 , the reinforcement effect of soft foundation by preloading with surcharge of fill is analyzed and evaluated .Through the deep horizontal displacement monitoring, side pile horizontal displacement monitoring and surface subsidence monitoring, the deformation law of soft soil foundation by preloading with surcharge of fill is grasped , loading rate is controlled , the preloading time is determined , the construction safety and engineering quality are ensured, the feedback to designer and guiding construction are achieved ,The results show that it is feasible to use preloading with surcharge of fill to treat the soft foundation.
