基于泊松曲线法的市政道路软土路基处理方法研究

Research on Soft Soil Subgrade Treatment Method of Municipal Roads Based on Bossung Curve Method

道路软土路基会造成路面裂缝、断裂及坍塌等问题的发生,增加了交通事故发生的概率,给人们的出行安全埋下了隐患。因此,文章研究了基于泊松曲线法的市政道路软土路基处理方法,选取Q工程为此次测试的主要目标对象,通过进行回填密实度测定,固定预压路基桩体,基于泊松曲线法建立沉降缓冲围护结构,采用动力固结法实现市政道路软土路基处理。测试结果表明:与基础Q工程软土路基测试组对比,基于泊松曲线法的Q工程软土路基测试组最终得出的泊松比相对更高,处理软土路基效果更佳,路基的承压能力更强。

The soft soil subgrade of the road will cause problems such as road surface cracks,fractures and collapses,increasing the probability of traffic accidents,and laying a hidden danger for people's travel safety.Therefore,this paper studies the soft soil subgrade treatment method of municipal roads based on Bossung Curve method.Q project is selected as the main target object of this test.By measuring the backfill compactness,the preloading subgrade pile body is fixed,and the settlement buffer retaining structure is established based on Bossung Curve method.The dynamic consolidation method is used to realize the soft soil subgrade treatment of municipal roads.The test results show that the Bossung's ratio of Q project soft soil subgrade test group based on Bossung Curve method is relatively higher compared with the foundation Q project soft soil subgrade test group,the effect of soft soil subgrade treatment is better,and the bearing capacity of subgrade is stronger.
