摘要
针对蓄水洞库这一新型水利工程,梳理并简述与洞库蓄水的特殊性相对应的蓄水洞库规模论证、设计标准确定、工程总体布置和结构方案、洞库充水泄水的水力调控、洞内消能、洞库压力状态、通气排气、气爆防治、水质控制、泥沙防治、环境影响、施工技术等关键问题,提出研究和解决方向,为建立蓄水洞库技术体系提供借鉴.研究表明:洞库蓄水在安全、政策处理等方面有突出优势,但存在水力调控、通气排气、气爆防治等特定的技术问题,需要开展研究和探索.
Abstract
Water storage caverns are a new type of water conservancy projects.This paper summarizes and briefly discusses the key issues related to the particularity of water storage caverns,such as the demonstration of the scale of water storage caverns,determination of design standards,overall layout and structural scheme of the project,hydraulic regulation of water filling and discharging in caverns,energy dissipation in caverns,pressure state of caverns,ventilation and exhaust,gas explosion prevention and control,water quality control,sediment prevention and control,environmental impact,construction technology,etc.This paper also proposes research directions and solutions,aiming to provide references for establishing a technical system for water storage caverns.Resnlts show that storing water in the cave depot have outstanding advantages in safety and policy handling,but there are specific technical issues such as hydraulic regulation,ventilation and exhaust,and gas explosion prevention,which require research and exploration.
