以杭瑞黔西毕都高速抵母河特大桥都格岸错落体为研究对象,采用离散块体理论并结合桥区工程地质条件,通过分析错落体还原-裂隙张开、断裂和滑移分析模型,研究错落体稳定性和合理的溶蚀卸荷裂隙结构面参数问题,反分析获取溶蚀卸荷裂隙的结构面参数进一步分析桥区工程岸坡稳定性提供重要依据,具有可靠性和参考指导价值。 Based on the discrete block theory and the engineering geological conditions in the bridge area, the paper analyzes the fault-fracture-fracture, fracture and slip analysis models of the fault- Studying the stability of the patchwork and the reasonable parameters of the fracture surface parameters of the dissolution and unloading fracture, the back analysis of the parameters of the fracture surface of the dissolution and unloading fracture provides an important basis for further analysis of the slope stability of the bridge area engineering project, and has the reliability and reference value.
