袖阀式劈裂注浆和动力固结法路基补强处理

Stiffening Treatment of Subgrade by Sleeve-Valve Type Split Grouting and Dynamic Consolidation Method

结合工程实例,对道路下雨污水管槽回填密实度不满足设计要求而导致的路面开裂,采取袖阀式劈裂注浆法和动力固结法进行加固,并分析影响加固效果的原因以及总结值得吸取的经验教训。

In combination with the project example for the pavement cracking due to back fill density of rainwater and se￣wage pipe trough under roads not meet the design requirement,it should be consolidated by sleeve-valve type split grouting method and dynamic consolidation method.At the same time,the paper analyzes the cause of influencing on consolidation effect and summarizes the experience lesson to be worth draw.
