【摘要】 采用四种离心模型试验方案,对不同布置方式、不同压实度情况下的土工合成材料处理桥头过渡段路基的沉降变形进行了研究,得出土工合成材料处理的主要作用是使过渡段路基台阶型沉降转化为沉降坡差,而不是降低沉降至某一值,并且得出上部密长的半断面布置为最优布置的结论。更多还原

【Abstract】 Using four centrifugal tests,this paper studied the settlement of the embankment at the bridge approach where the geosynthetics were disposed differently and the embankment were in different compactnessThe conclusion is that the main function of geosynthetics is to transform the embankment’s settlement from sidestep to gradient,but not to reduce its settlement to some extent,and the geosynthetics should be long and disposed in small vertical space in the upper half of the profile,which will have better effect更多还原
