三峡电站等工程采用下游坝面钢衬钢筋混凝土管道,这种管道型式新颖,无规范可依。在 运行时管壁混凝土开裂,及在温度荷载作用下应力和变形情况如何,是这类管道结构中尚未 解决的重要问题之一。通过仿真材料模型试验及非线性有限元法,对带裂缝的钢衬钢筋混凝 土 管道在内外温度差作用下的温度应力及变形进行了研究,获得了可靠的成果,为管道设计提 供了重要依据。　

Steel lined reinforced concrete penstock built on the downstream surface of dam is used in TGP's power station.This kind of penstock is of a novel style.There fore,How will be the stress and strain statuses of penstock occurring cracks and under the action of temperature load in the operating period is still one of i mportant problems not being solved.By means of simulating model experiment and n onlinear fininte element method,the research on temperature stress and strain un der the action of temperature differences between the inner and outside of steel lined reinforced concrete penstock was performed.The reliable results were ob tained,and primary basis for pipe line design was provided
