新疆某工程鱼道边坡工程地质评价

两岸山体开挖后形成的边坡稳定性往往影响鱼道的安全运行,边坡垮塌、鱼道淤积往往是造成鱼道失效的常见地质灾害,在鱼道建设之前对鱼道边坡、附近冲沟等不良地质现象进行工程地质评价,并采取工程措施,避免鱼道后期运行受到地质灾害的影响显得尤为重要。介绍新疆某工程鱼道边坡坡度、高度、地形、地貌、结构面发育状况,对结构面分级,定性分析了三级结构面对边坡的稳定性影响,评价及其对后期鱼道运行的影响程度,提出边坡开挖建议值0.35~0.5,并给出边坡开挖和保护建议。

Engineering Geological Evaluation of Fishway Slope of a Project in Xinjiang

Slope stability formed after excavation of mountain bodies on both banks often affects the safe operation of fishway.Slope collapse and fish channel silting are often common geological disasters that cause fish channel failure.Before the construction of fishway,it is very important to carry out engineering geological evaluation on adverse geological phenomena such as slope of fishway and nearby gully,and take engineering measures to avoid the impact of geological disasters on later operation of fishway.This paper introduces the slope,height,topography,landform and development status of structural surface the fishway slope in Xinjiang,classifies the structural plane,qualitatively analyzes the influence of the three-level structure on the slope stability,evaluates its influence on the later fishway operation,puts forward the recommended value of slope excavation 0.35-0.5,and gives the suggestions for slope excavation and protection.
