| 摘 要： | 介绍了软土地基上桥坡的沉降、分层沉降、水位及孔隙水压力的监测成果。分析了桥坡沉降、沿桥坡纵向的展开曲线，桥坡沉降的竖向分布规律及孔隙水压力的变化。结果表明，注浆加固和真空井点降水后有一定的加固作用，其工后沉降减小，纵坡变化减小。从桥坡沉降的竖向分布规律来看，主要压缩量发生在灰色淤泥质土层中。

| Abstract: | in this paper presented are the results of monitoring of settlement of ground. layer-wise settlement. ground waterlevel and pore water pressure for approaches to bridge abutments on soft soil foundation. Settlements. settlement distributionalong the roadway. compression in the vertical section and the change of pore water pressure have been studied. It is seen thatgrouting and vacuum well point are useful in reducing post construction settlements and the change of longitudinal grade alongthe roadway. and that settlement lies mainly in the grey mucky layers. |
