高速公路采空区地基注浆施工技术

当前国内部分高速公路上进行了采空区治理的试验研究工作,特别是对注浆充填法的应用,积累了一定的经验,但尚未形成规范或规程,设计施工主要以经验为主,缺乏系统实践体系.结合工程实践经验,针对某公路采空区地基情况,就注浆材料的优选,以及注浆施工工艺设计等方面进行了探讨,旨在为高速公路下伏采空区注浆处治提供科学的施工技术,为同行提供参考.

Technology of Expressway Goaf Foundation Grouting Construction

In recent years, researchers have carried out experimental study work concerning about ing mined-out area on some part of expressway, especially the application of grouting which has accumulated certain experience, but has filling govern- method, not yet formed a specification or regulations. Design and construction are mainly composed of experience lacking practice system. This paper are based on the engineering practice experience, focusing on some highway mined-out area foundation to discuss the grouting material optimization and grouting construction technology design and so on, aiming at providing a scientific construction technology of grouting method for expressway as well as a reference for peers.
