窄口水库位于黄河一级支流弘农涧河上,是一座以防洪为主,兼顾灌溉,结合发电、养鱼、旅游、工业及生活供水等综合利用的大(Ⅱ)型水利枢纽工程。本文根据溢洪道右岸边坡区地质测绘、钻探、物探、坑探资料,采用赤平投影、手册计算及有限元分析法,分不同的工况进行分析计算,从而研究评价了该边坡稳定性,客观地评估了其地质灾害危险性,提出了合理的工程处理措施建议,为除险加固工程设计提供科学依据。
Located on the Hongnongjian River, a tributary of the Yellow River, the narrow-mouth reservoir is a large-scale (Ⅱ) -type water project that is mainly flood control and combines irrigation, power generation, fish farming, tourism, industrial and domestic water supply and other comprehensive utilization. Based on the geological mapping, drilling, geophysical exploration and pit exploration data of the right bank slope area of the spillway, the project is analyzed and calculated in different working conditions by using stereographic projection, manual calculation and finite element analysis, so as to evaluate the stability of the slope, Objectively assessed the risk of its geological disasters, put forward reasonable suggestions on engineering measures and provided a scientific basis for the project design of reinforcement and reinforcement.
