砂砾石层地质边坡在开挖过程中岩体性质及岩体结构变化较大,设计阶段要对砂砾石地基防渗填筑引水渠道的边坡渗流及稳定性进行计算分析。文章就渠道渗流计算和边坡稳定计算过程中的注意事项进行阐述,为设计方案优化提供充分数据支撑。为边坡加固处理设计施工提供有利资料支撑。 During the excavation process, the rock mass properties and the rock mass structure change greatly. In the design stage, the slope seepage and stability of seepage control and filling diversion channel of sand and gravel foundation should be calculated and analyzed. The article elaborates the considerations in the calculation of seepage flow and slope stability calculation, and provides sufficient data support for the design optimization. For slope reinforcement design and construction to provide favorable information support.
