摘　　要：该文以上海市奉贤区大叶公路与团青公路修复工程作为主体依托工程,对课题研发的新型道路注浆材料配合比设计、新型复合式注浆工艺的设计及作用机理、配套施工工艺及方案设计等方面做出了阐述和分析。试验结果表明,该工程中采用的新型快硬性无机道路注浆材料的注浆效果要优于传统地聚合物注浆材料;采用复合式注浆加固工艺的注浆效果要优于采用常规闷头管注浆加固工艺的注浆效果,且可大幅度提高注浆效率,符合道路修复快速开放交通的需求,并提出了基于新型注浆材料和复合式注浆工艺下的推荐注浆方案设计。Relying on the main project of Shanghai Fengxian Daye Highway and Tuanqing Highway Repair Project, the article sets forth and analyzes the mixing ratio design of the new road grouting material, the design and action mechanism of the new composite grouting technology, and the supporting construction technology and scheme design researched and developed in the subject. The test result shows that the grouting effect of the new fast hardening inorganic road grouting material used in this project is more excelled than the traditional polymer grouting material, and the composite grouting reinforcement technology is more excelled than the conventional bulkhead pipe grouting reinforcement technology, which can greatly improve the grouting efficiency and satisfy the request of fast opening the traffic after the road repair. The article puts forward the recommended grouting scheme design based on the new grouting material and the composite grouting technology.
