一、重力坝下游坝面压力管道的布置本文针对下游坝面钢衬钢筋混凝土压力管道的布置和结构进行了分析研究。下游坝面管的主要优点是:(1)避免坝体混凝土与钢管安装施工之间的干扰,加快施工进度,提前发电受益。(2)这种布置对混凝土坝体削弱不多,有利于保持大坝整体性。(3)将管道布置在坝体轮廓线以外,内水压荷载基本不传递到坝体 First, the gravity dam dam surface pressure pipe layout This article aimed at the downstream dam steel liner reinforced concrete pressure pipe layout and structure were analyzed. The main advantages of the downstream dam surface pipe are: (1) to avoid the interference between dam concrete and steel pipe installation and construction, speed up the construction progress, benefit in advance power generation. (2) This arrangement weakens the concrete dam, which is good for keeping the integrity of the dam. (3) The pipeline layout outside the contour of the dam, the internal hydraulic load is basically not passed to the dam
