摘　　要：随着我国改扩建高速公路的快速发展,加筋土路基在改扩建高速公路中的应用不断加强,能够加强公路整体结构的稳定性,提高新老路基的协同变形,减少新老路基拼接部位不均匀沉降,避免了在施工中和通车后路面出现纵向裂缝和路基塌陷,为进一步掌握加筋土挡土墙施工技术要点,本文以某高速改扩建工程为例进行分析,总结土工格栅加筋土挡土墙施工的技术要点,以提高改扩建高速公路路基的拼接质量,为类似工程提供参考。With the rapid development of China’s expressway reconstruction and expansion,the application of reinforced earth roadbed in expressway reconstruction and expansion is constantly strengthened,it can strengthen the overall structural stability of highway,improve the cooperative deformation of the new and old roadbed,reduce the uneven settlement of the new and old roadbed splicing part,and avoid the longitudinal cracks and collapse of roadbed during construction and after traffic,in order to further grasp the technical points of reinforced earth retaining wall construction,this paper takes a high-speed reconstruction and expansion project as an example to analyze and summarize the technical points of geogrid reinforced earth retaining wall construction,so as to improve the splice quality of the reconstruction and expansion highway roaded and provide reference for similar projects.
