摘要/Abstract

摘要： 水工有压隧洞的压力计算是一个在设计中必须解决的水力学问题。从有压恒定流的伯诺里方程出发，对有压隧洞出口段的压力变化规律进行了理论分析，提出了理论计算式，并以工程中常见的几种出口型式为例，具体分析了其压力性质。

Abstract: The hydraulic calculation of pressure tunnel is a hydraulics issue needed to be solved in design. From Bernoulli's Energy equation of steady uniform pressure flow, this paper theoretically analyzes the laws of pressure changes of outlet of pressure tunnel and gives some computation formulas of theory. In combination with several forms of outlet that frequently used in practical projects, this paper analyzes the characteristics of pressure specifically.
