摘要
纵向裂缝是沿河公路的主要病害之一。利用有限单元法,对粉喷桩、桩板式挡土墙、钻孔压浆等3种处治效果进行了数值分析。计算结果表明:粉喷桩处治能显著减小新老路基的路面沉降和水平位移,消除裂缝效果最好;钻孔压浆次之;桩板式挡墙一般。结论有助于沿河路基纵向裂缝处治方法的选择和优化。
Longitudinal crack is one of the main diseases of embankment along rivers. Numerical analysis are carried out to evaluate the effectiveness of three treatment methods of dry jet mixing, drilling pressure slurry and pile-board ward wall by using finite element method in this study. The results indicate that the dry jet mixing technique can reduce vertical settlement and lateral deformation of widening and existing embankment. This result demonstrates that the dry jet mixing technique is the best suitable measure to eliminate longitudinal cracks than drilling pressure slurry technique and pile-board ward wall. The conclusions will help to optimize treatment techniques of longitudinal crack of embankment along rivers.
