摘要
为了减轻暴雨工况下地表水及地下水对加固后第四系边坡稳定性的影响,采用了暴雨径流量的计算方法,得出了第四系边坡位置处的暴雨强度,暴雨径流量,研究了明渠恒定均匀流的水力特性和计算理论,得出了水力最优断面,截水排水沟的设计参数,探讨了现场第四系边坡涌水量大小和空间分布特征,得出了水平放水孔的设计参数。
In order to reduce the effect of surface water under heavy rain conditions and groundwater on the fourth slope stability after reinforcement,this article adopts the calculation method of rainstorm runoff,concludes the rainstorm intensity of the quaternary slope location,storm runoff,studied the hydraulic characteristics of constant flow in open channel uniform flow and calculation theory,obtains the optimal hydraulic section,sectional water drain design parameters,discusses the water inflow and spatial distribution characteristics of the quaternary slope and obtains the design parameters of the horizontal discharge hole.
