- 摘要:
- 调查了锦屏二级水电站厂址区边坡的基本地质条件，根据边坡的岩体结构特征，从结构面的不同规模及岩体结构的不同层次去研究斜坡变形破坏模式，将其分为整体破坏模式和局部破坏模式；从不同岩性的角度又将其分为基岩斜坡和堆积层岩体结构斜坡。并分别分析了边坡的变形破坏机制，最后应用地质分析和稳定性计算对边坡的稳定性进行了评价，得出岩质边坡整体稳定性较好，第四系堆积体边坡在最不利组合工况下处于基本稳定-潜在不稳定状态，表部局部存在块体失稳可能。
- Abstract:
- The basic geological conditions of the water exit port of JinpingⅡhydroelectric station is investigated.According to the rock structure characteristics of the slope as well as deformation-destruction pattern which is study on different scale of the structural plane and different level of the rock structure,the deformation-destruction pattern can be divided into two kinds of patterns,the global destruction pattern and the local destruction pattern;according to different angular of rock characteristic,it could be bedrock and accumulative formation slope.The formation-destruction mechanism is analyzed.In the end the stability is evaluated by using geology analysis as well as stability calculation and it is generalized that the global stability of this rock slope is well and the Quaternary talus slide is in basic stabilization-potential instabilization situation,at the same time,part of the surface has the possibility of block destabilization.
