为解决人工挖孔灌注桩施工过程中塌孔病害,结合工程实际,在对山区陡坡环境岩土情况分析的基础上,归纳总结了病害的类型与特点;探讨人工挖孔灌注桩塌孔的成因;提出了针对性的工程处治技术。 In order to solve the problem of tunnel collapse during the construction of artificial digging and pouring pile, the types and characteristics of the disease were summarized and summarized based on the analysis of the engineering conditions of the rock and soil in the steep slope of mountainous area. Proposed targeted engineering treatment technology.
