摘　　要：本文提出了一种后张法预应力光弹性实验方法与技术，并用该方法解决了三峡工程升船机的试验机─－清江隔河岩水利枢纽第二级垂直升船机承重结构的楼板与深梁的预应力分析问题，实验结果已被工程单位所采用。A poststressed experimental method and relevant technique are proposed in this paper. A prestrssrd analysis problem of undertake structure of Qing river Ge He Yan key water control projets's vertical ship-lifting machine, which is the testing machine of the San Xia engineering, is solved by using this method. The experimental results put forward in this have been adopted by the engineering department.
