摘　　要：公路路基沉陷病害一直困扰着工程界,大量工程案例研究表明,注浆补强施工技术对于处治公路路基沉陷病害具有显著作用,且不同注浆补强工艺在处治路基沉陷病害中的作用和机理存在较大差别。本文特以注浆补强工艺的工程应用为研究对象,对常用的袖阀管注浆补强技术和花管注浆补强技术进行了详细分析,明确了上述两种路基补强工艺的施工流程和关键环节。Highway subgrade subsidence has been perplexing the engineering community. A large number of engineering case studies show that grouting reinforcement construction technology plays a significant role in the treatment of highway subgrade subsidence, and the role and mechanism of different grouting reinforcement technology in the treatment of subgrade subsidence are quite different. In this paper, the engineering application of grouting reinforcement technology is taken as the research object, and the common sleeve is used. The technology of valve pipe grouting and flower pipe grouting is analyzed in detail, and the construction process and key links of the two kinds of subgrade reinforcement technology are clarified.
