龙羊峡水电站的压力引水管道通过坝体,直径为7.5米,最大水头150米,包括水锤压力在内,内水压力近18公斤/厘米~2。在均匀内水压力作用下,坝体混凝土内圆形钢管的钢板和混凝土的应力状态如何?在以往的工程设计中,有的仅考虑钢衬单独承压;有的考虑钢筋和钢衬的作用;有的考虑钢衬、钢筋和混凝土共同作用。这关系到如何合理确定内水压力在钢衬和混凝土之间的分配,以及如何节约钢材、减薄钢衬厚度的问题,很值得研究。一些已运 Longyangxia Hydropower Station pressure diversion pipeline through the dam, a diameter of 7.5 meters, the maximum head of 150 meters, including water hammer pressure, including water pressure of nearly 18 kg / cm ~ 2. Under the uniform internal water pressure, what about the stress state of the steel plate and concrete in the circular concrete pipe in the dam concrete? In the past engineering design, some only consider the steel liner alone bearing pressure; some consider the function of steel bar and steel lining Some consider the steel liner, steel and concrete work together. This is related to how to rationally determine the distribution of internal water pressure between steel lining and concrete, and how to save steel and reduce the thickness of steel lining, which is worth studying. Some have shipped
