老口航运枢纽泄水闸坝消能防冲设计

摘要

Laokou Navigation Complex is a multi-purpose project privileged to navigation and flood control,com⁃bined with power generation and water environment improving of Nanning City. The energy dissipation and scour prevention design of discharging gate dam must be able to minimize scouring to downstream riverbed while permit⁃ting normal operation of shiplock lower approach and power station. The results of hydraulic model test demonstrate that downstream stilling basin of gate dam renders energy dissipating effect up to design requirements.%　　老口航运枢纽工程是一座以航运、防洪为主，结合发电，兼顾为改善南宁市水环境创造条件的综合性枢纽。泄水闸坝的消能防冲设计应满足船闸下引航道和电站正常运用的要求，减轻对下游河床的冲刷。通过水工模型试验的验证，泄水闸坝的闸下消力池消能效果基本满足设计要求。
