| 摘 要： | 采用土工格栅加筋处理路堤填土可有效解决路堤填土压缩变形过大的问题,从而减小路桥过渡段桥台与路堤的差异沉降以及缓解桥头跳车的现象.通过现场试验对加筋路堤中格栅上、下表面土压力与格栅变形进行了监测分析.采用有限元方法对比分析路堤在加筋与未加筋2种工况下路桥过渡段路堤变形的差异.结果表明：路堤加筋技术在桥台附近减载作用明显,...

| Abstract: | Geosynthetic can be used to reinforce the embankment fill so that it can solve problems of excessive compression effectively,thus reduce differential settlements between bridge abutment and embankment and alleviate bump at the approach of the bridge.The stress and deformation of the soil above and below the geosynthetic were measured through the field test.In addition,the differential settlements at the bridge approach under two conditions(embankment with and without geosynthetic reinforcement) were analyze... |
