土工格栅在治理软土路基沉降问题中的研究

Research on using geogrids to control settlements of subgrades

对土工格栅在治理某高速公路软土地基的沉降问题进行了研究,介绍了加固软土路基的处理方法和治理机理,并采用有限元分析方法,对处理后的路基沉降进行了计算,所得结果与实测沉降值偏差较小,证明本研究采用的计算理论和结构模型以及编写的程序是正确的。

The mechanism and method of Geogrids in harnessing soft foundation of expressway are analyzed. According to finite element method, the settlement calculation results approach the practical measurement results.The calculation method and construction model are proved to be correct.
