摘要
详细介绍了采用压力注浆法对采空区引起的公路路基塌陷进行治理的施工情况.治理后的地基承载力达到了规范要求,说明该种方法在治理采空区引起的公路路基塌陷是可行的.在采用压力注浆法治理公路路基塌陷时,需要通过注浆试验确定合理的设计参数、选择性能良好的施工设备、制定切实可行的施工工艺以及一套完整的质量保证体系.
The author in detail introduces application of pressure grouting penetration in treatment for foundation dent that has keen caused by goaf in the paper. The bearing capacity of foundation treatment attains normative require that illustrates the grouting penetration is practical in treating foundation dent caused by goat＇. The engineers and technicians determine reasonable design parameter, choose wellbehaved construction equipment, draw up operable construction procedure and a set integrated quality system by test in the process of making use of grouting penetration method treating foundation dent.
