三峡溢流坝段几个温度应力问题的计算与分析

Computation and Analysis of Some Problems of Temperature Stress of Spillway Dam Section in the Three Gorges Project

本文对三峡溢流坝段通仓浇筑与不同分缝分块、孔口、溢流面的温度应力进行了全面分析,并在此基础上提出了三峡溢流坝段施工设计中需要考虑的问题。这些问题具有代表性,也可作三峡其它坝段以及类似工程进行施工方案、温控设计时参考。

This paper deals with problems of temperature stress of the spillway dam section in the Three Gorges Project with relation to pouring without longitudinal joint,varied blocks of dam,spillway outlet, spillway face. Based on the above analysis,the problems,which require attention in the construction design of spillway dam section, are advanced. These problems have representativity and are of referencing value for working of construction scheme and temperature control in other dam sections of Three Gorges dam and analogous projects.
