新疆某水库工程泄水建筑物水力特性试验成果与分析

Test Results and Analysis of Hydraulic Characteristics of a Reservoir Project Discharge Structure in Xinjiang

泄水建筑物作为水利工程重要组成部分,其体型和出口消能设施的设计合理性是关系水利工程安全建设和运行的重要因素之一。为保证泄水建筑物满足设计要求,同时保证工程安全运行,通过室内水工模型试验,分别观测各泄水建筑物泄流能力、水流流态和水流冲刷等特性,综合分析泄水建筑运行的可靠性,论证设计方案的合理性,从而对设计方案进行优化。试验结果表明:导流洞、溢洪洞和泄洪洞基本满足设计要求,试验结果可为工程施工期和正常运行期的安全运行提供理论依据。

As an important component of hydraulic engineering,the design rationality of water release structures and outlet energy dissipation facilities is one of the important factors related to the safe construction and operation of hydraulic engineering.It is necessary to ensure that the discharge structure meets the design requirements while ensuring the safe operation of the project.This paper conducts indoor hydraulic model tests to observe the discharge capacity,water flow pattern,and water erosion characteristics of each discharge building,comprehensively analyzes the reliability of the operation of the discharge building,demonstrates the rationality of the design plan,and optimizes the design plan.The test results indicate that the diversion tunnel,spillway tunnel,and spillway tunnel basically meet the design requirements,and the test results can provide a theoretical basis for the safe operation of the project during construction and normal operation periods.
