摘　　要：笔者针对三门县某水库坝后护坡破损问题展开研究,通过岩石物理性能测试、化学成分分析和碱活性试验,探讨岩石破损的主控因素。研究发现:护坡岩石的物理性能不满足现行规范要求,内部微裂缝和孔隙显著降低了其强度和稳定性;化学风化作用在特定气候条件下加剧了岩石的劣化;尽管岩石不存在碱活性危害,但其物理和化学特性仍需通过工程手段加以改善。基于上述分析,提出了多种加固方案,包括重新铺砌、喷射混凝土加固、预制空心六角块生态护坡、植被护坡及混凝土框格梁等。这些措施能有效增强护坡的抗风化能力和稳定性,促进区域生态系统的平衡。研究成果为类似工程的病害诊断、修复设计及长期维护提供了重要参考。This study investigates the damage mechanisms of the slope protection behind a reservoir dam in Sanmen County.Through physical property tests,chemical composition analysis,and alkali reactivity tests of the rock materials,the primary controlling factors of rock degradation were systematically examined.Key findings include:The physical properties of the slope protection rock fail to meet current technical standards,with internal microcracks and pores significantly reducing its strength and stability;Chemical weathering processes under specific climatic conditions exacerbate rock deterioration;While no alkali-silica reaction risk was identified,targeted engineering interventions remain necessary to address the material's physical and chemical deficiencies.Based on these findings,multiple reinforcement strategies were proposed,including stone repaving,shotcrete reinforcement,eco-friendly precast hollow hexagonal blocks,vegetation-based slope protection,and concrete grid beams.These measures effectively enhance weathering resistance,structural stability,and ecological balance.The research outcomes provide valuable references for defect diagnosis,rehabilitation design,and long-term maintenance of similar hydraulic engineering projects.
