摘要
为研究拓宽路基的变形特性和相应的处置措施,文中采用有限元数值模拟手段对拓宽路基开展数值仿真模拟.结果表明,采用土工格栅对拓宽路基加筋后,能显著改善拓宽路基顶面的沉降变形.增加加筋层数能有效提高拓宽路基的极限承载力,在改善路基变形方面也有良好改善效果.在实际工程中,应尽量由上至下增加土工格栅加筋层数.
Abstract
In order to study the deformation characteristics and corresponding treatment measures of widening roadbed,the finite element nu-merical simulation method is used to carry out the numerical simulation of widening roadbed,it can obviously improve the settlement deforma-tion of the top surface of widening roadbed.Increasing the number of reinforced layers can effectively improve the ultimate bearing capacity of widened roadbed,and also has a good effect on improving the deformation of roadbed.In practical engineering,the number of geogrid rein-forced layers is increased from top to bottom as far as possible.
