在对南京内金川河主流河道挡墙泄水孔调查的基础上,对泄水孔的泄水功能进行了分析研究,旨在为泄水孔的优化设计提供依据。分析认为,内金川河主流河道挡墙的绝大多数泄水孔位于墙后潜水面以上,无饱和重力水可排,但它们的泄水功能基本是好的;个别地段的少量泄水孔位于墙后潜水面以下,常年呈泄水状态,且有一定的流量,目前的泄水功能正常。建议在对局部挡墙进行重新设计施工时优化对泄水孔的布置。 Based on the survey of the retaining wall spillway in the mainstream of Jinchuan River in Nanjing, the drainage function of the spillway is analyzed and designed to provide the basis for the optimal design of the spillway. According to the analysis, most of the drainage holes in the main river retaining wall of the Inner Jinchuan River are above the diving surface behind the wall, and no saturated gravitational water can be discharged, but their drainage function is basically good. A few drainage holes in individual sections are located at Submersible surface below the wall, the year was a state of drainage, and have a certain flow, the current normal drainage function. It is suggested to optimize the arrangement of the scuppers when redesigning the partial retaining wall.
