【摘要】 为了解决填挖交界路基非均匀沉降 ,在填土中分层铺设土工格网等土工加筋材料 ;通过非线性有限元计算分析 ,结合现场沉降观测、FWD弯沉检测 ,研究了土工格网处治填挖交界路基非均匀沉降的机理。在此基础上 ,根据理论分析 ,提出了土工加筋材料处治填挖交界路基非均匀沉降的设计方法。更多还原

【Abstract】 Authors place reinforcement materials such as geonets layered in the filling soil in order to solve the problem of unequal settlement of subgrade at the cut to fill location.In this paper, by using nonlinear FEM, authors analyzed the mechanism of using geonets to treat this kind of unequal settlement based on tests on settlement and deflection by FWD in site. So,the design method using reinforcement materials to treat this kind of unequal settlement is put forward.更多还原
