| 摘 要： | 结合武汉绕城公路,针对软土地基上新老路堤搭接中存在的岩土工程问题进行了分析,提出了处理对策,并通过理论分析和原位监测成果进一步说明了采用粉喷桩处理软土地基、土工格栅增强新填路堤刚度、结合面开挖反坡和控制路堤填筑质量是十分必要的.

Geotechnical problems caused by new embankment splicing with old one on soft ground and treatment measures |
| |
| Abstract: | Based on the example of Wuhan Ring Expressway, this paper analysed the geotechnical problems caused by new embankment splicing with old one on soft ground; and brought forward some treatment measures. The results of theoretic analyses and site monitoring proved that it is quite necessary to take such measures as soft ground treatment by dry jet mixing pile; enhancing the rigidity of new embankment by geogrid; forming adverse gradient of interface;and control quality of embankment filling. |
