| 摘 要： | 近年来,国内各地相继出现了公路路基支挡结构物失稳事件,对相关路桥的运营安全造成了严重威胁。由于条件特殊及环境制约,此类工程加固难度很大。结合山东省G104界河立交桥加筋土挡土墙和G205高峪铺公铁立交桥坡间挡土墙的加固,对此类工程失稳的特征、原因及相应的工程对策从理论到实践展开了深入研究,并得到了具有一定推广价值的结论。

| Abstract: | In recent years, many bracing structures of roadbed are failed in China. This is very danger to the roads and bridges. It is very difficult to reinforce these structures because of the special condition and environment. This paper studies the failure characteristics, reasons and engineering methods to treat the failure structures. The reinforcement projects of Jiehe cloverleaf junction on 104 national road and Gaoyupu gallop bridge on 205 national road in Shandong Province have been carried out as engineering background. Some conclusions with extensive value have been drawn. |
