文章所介绍的黄土隧洞压力钢管全线为地下埋管,结合压力钢管主、岔、支管的总体布置、水力计算等,阐述了钢管设计原则,由内水压力确定管壁厚度,用抗外压稳定进行复核。在贴边岔管结构计算时,根据规范公式,计算补强板的宽度和厚度,并对补强板边缘应力进行近似验算,针对计算结果进行分析,确定合理的补强板有效宽度和厚度。
In this paper, the whole tunnel of pressure pipe for loess tunnel is underground buried pipe. Based on the main layout, hydraulic calculation and so on of the main, branch and branch of the pressure pipe, the design principle of the pipe is elaborated. The pipe wall thickness is determined by the internal water pressure, Review. When calculating the structure of bifurcated bifurcated pipe, the width and thickness of the bracing plate are calculated according to the canonical formula, and the approximate calculation of the edge stress of the bracing plate is performed. The calculation results are analyzed to determine the effective width and thickness of the stiffener.
