摘要: 岩质高边坡的稳定性直接影响到水电站建设的顺利进行。西南某水电站右岸高边坡岩体卸荷深度大,岩脉、断层、裂隙发育,且施工开挖规模大,边坡在施工过程中出现了大量裂缝,对后续施工和运行期的稳定性产生极其不利的影响。针对该水电站岩质高边坡出现裂缝的现象,结合该边坡的地质资料、监测成果及施工情况,综合分析了边坡出现裂缝的原因,并提出了相应的工程治理措施,对类似工程的勘探、监测分析和工程治理具有一定的参考价值。

Abstract: The stability of high rock slope has a direct impact on the smooth construction of a hydropower station. Due to large unloading depth and developed dikes, faults and fissures, as well as large-scale excavation, a large number of cracks occurred in the excavation of the right bank slope of a hydropower station in southwest China, which would produce unfavorable influences on the subsequent construction and the stability during operation period. Based on the cracks of high rock slope and according to the geological data, monitoring results and construction conditions, the causes of cracks are analyzed comprehensively and the corresponding engineering treatment measures are suggested, which may provide references for the exploration, monitoring and engineering treatment of similar projects.

Key words: rock slope ,    causes of crack  ,   safety monitoring
