摘　　要：针对在长期复杂的自然环境条件和各种荷载作用下,土石坝容易产生安全隐患的问题,针对四合水库坝体除险加固工程中坝体进行了初步设计,并分别应用两种方案极限平衡法和有限单元法对坝体在多工况下:校核水位、设计水位、正常水位以及水位骤降条件下进行抗滑稳定性分析,结果表明:应用有限元法更能反映坝体的稳定性情况,该研究为同类坝体的安全鉴定、加固提供借鉴。Dam is easy to generate potential safety hazard in the long-term complex natural environmental conditions and various loads.Especially, because of careless design, poor-quality construction and unsuitable management, many problems may be encountered for the safety of earth-rock dams built earlier.The article makes preliminary design for the dam in Sihe reservoir dam danger-eliminating project, and applies limit equilibrium method and finite element method separately to stability against sliding analysis under check water level, designing water level, normal water level or suddenly failed water level such different situations to ~rnish experience for the same dam＇s safety appraisal and reinforcement.
