复杂滑带条件下的岩体 参数反演研究

结合1967年稚碧江唐古栋滑坡1 -1剖面模型，综合比较分析了相关岩体各工况下的稳定性，确定了最危险工况，以极限平衡原理确定了最危险滑面下强度参数，并取其满足规范要求的最低稳定性标准为反演目标。由于滑带可能穿越不同的岩层，反演过程中需要分别对不同岩层进行危险滑带搜索，以确定未知岩层的力学参数。结果显示岩体参数反演在工程上具有较高的可靠性，可为实际边坡工程提供重要的依据。

Study on inversion of rock mass parameters under condition of complicated sliding zone

Based on the 1-1 profile model of Tanggudong Landslide of Yalongjiang River occurred in 1967,the stability of the relevant rock mass under various conditions are comparatively analyzed and the most dangerous condition is determined,the then the strength parameters under the most dangerous sliding surface are also ascertained with the limit equilibrium principle;for which the minimum stability standard that meets the requirement of the relevant specification is taken as the objective of the inversion.As sliding zones may crosses through various rock strata,the dangerous sliding zones must be searched for different strata during the inversion,so as to identify the mechanical parameters of the unknown strata.The results show that the inversion of rock mass parameters has a higher reliability in engineering and then can provide an important basis for the actual slope project concerned.
