加宽土工格栅加筋施工技术在公路路基中的应用

Application of Widening Geogrid Reinforcement Construction Technology in Highway Subgrade

结合某高速公路改建工程实际情况,围绕高速公路路基加宽施工过程中的土工格栅加筋优化技术展开全面探讨,具体包括施工准备、加筋土工格栅铺设、底层土工格栅铺设、上层土工格栅铺设、施工质量验收等不同施工环节。实践证明,应用土工格栅加筋技术对于有效平衡路基土体应力,提高路基加宽施工质量,保证交运运输安全具有重要意义。

Combined with the actual situation of a highway reconstruction project,the optimization technology of geogrid reinforcement in the process of subgrade widening construction is comprehensively discussed,including construction preparation,geogrid reinforcement laying,geogrid laying at the bottom layer,geogrid laying at the upper layer,construction quality acceptance and other different construction links.It has been proved that geogrid reinforcement technology is of great significance to effectively balance the stress of subgrade soil,improve the quality of subgrade widening construction and ensure the safety of transportation.
