关于大型渡槽结构设计的几个问题
|
摘要
大型渡槽是中国南水北调工程中的关键性水工建筑物,其输水流量比目前世界上已建渡槽的流量要大得多,由此产生了一些新的渡槽结构以满足巨大的输水流量。由于目前没有大型渡槽的结构设计规范,一些结构问题,如结构抗震、抗风设计、剪力滞、温度应力等,还困扰着结构工程师。通过对大型渡槽结构设计中几个问题的分析,初步阐述了大型渡槽结构设计的若干理论和方法,并对一些可能的结构问题进行了预测和讨论。
Large-sized aqueduct is a kind of key hydraulic structure in the China South to North Water Transfer Project.Because the discharge of the project is much bigger than that of the aqueducts constructed in the world,it is necessary to design a new kind of aqueduct structure in order to satisfy the requirement of large discharge conveyance.However,several structural problems including structural earthquake resistance,wind proof design,shearing force mitigation,and temperature stress alleviation still bother the structural engineers.Through analysis of the problems related to large-sized aqueduct structure design,the theories and methodologies for the design of large-sized aqueduct are expatiated,and several possible structural problems are predicted and discussed.
