| 摘 要： | 武荆高速公路天门连接线改扩建工程中,需要对新老路基土的强度差异进行准确评价,为新老路基处治方案设计提供依据。采用十字板剪切试验手段,对相同深度下新老路基土的强度进行了对比研究,并与钻孔取样室内试验结果进行了比较,发现十字板剪切试验是一种评价拓宽新老路基土强度差异的较好方法。

| Abstract: | In the widening project of Tianmeng highway connecting line to Wu-jing Expressway,the strength difference between soft soil under old and new embankment should be exactly assessed.The assessment can provide scientific basis for the soft ground treatment design.The vane shear test was adopted to compare the strength between old and new embankments with the same depth.In addition,the results of indoor soil tests also were compared with the vane shear tests results.The results show that the vane shear test is ... |
