| 摘 要： | 利用离心模型研究了软土地基上高速公路加宽中筋材拉应变和新老路堤变形特性.离心模型试验结果表明,土工格网铺设在软基和路堤之间比铺设在加宽路堤中部加筋效果显著,同时加筋可以降低加宽路堤的差异沉降.为较为全面分析加宽工程加筋路堤性状,采用大型有限元软件ABAQUS对离心模型试验进行了数值模拟.数值模拟和离心模型试验结果具有良...

| Abstract: | The tensile strain of the geogrid and the behavior of a reinforced embankment before and after expressway widening on soft ground were explored using the technique of centrifuge mode tests.The test results show that the effect of the geogrid reinforcement between the soft foundation and embankment is more obviously than that in the middle of the widened embankment,and the reinforcement with geogrid in the new embankment can reduce the differential settlement.To analyze the behavior of a reinforced embankmen... |
