| 摘 要： | 通过对某高速公路软基上出现病害的涵洞的变形监测和调查分析,对涵洞病害进行了分类,分析了这些病害产生的原因,提出了预防措施。分析表明,软基上涵洞的主要病害是地基不均匀沉降和侧向位移造成的。为减少涵洞病害,应合理确定软基处理深度、减少软基承担的荷载,涵洞宜采用整体式基础。

| Abstract: | Based on deformation monitoring and investigation for culverts encountering defections on soft ground of a expressway,the defects have been sorted out.The causes have been analyzed and the countermeasures have been pointed out.It has been shown from the analysis that the main causes for defects of culverts on soft ground lies in the differential settlement and lateral displacement of foundation.In order to reduce defects of culverts,measures to reasonably determine the treatment depth,to reduce the load on the soft ground,and to choose integral foundation for the culverts shall be taken. |

| Keywords: | defects of culvert differential settlement lateral displacement |
