| 摘 要： | 针对在高拱坝中普遍存在的陡坡坝段温度应力集中问题，以典型工程为例，采用一种新的结构分缝形式，应用三维有限元程序，对陡坡坝段从施工期到运行期的温度场、应力场进行仿真计算，通过改变结构分缝形式，为解决高拱坝陡坡坝段的应力集中问题寻找一条新的途径。

| Abstract: | So far as the problem of thermal stress concentration widely existed in the steep slope section of high arch dam is concemed, a new type of structural jointing is adopted by taking a typical project as the actual case, for which the temperature field and stress field of the steep slope section of the dam during the period from construction to operation is simulated based on 3- Dfinit element program. Through the modification of the structural jointing, a new method to solve the problem of the thermal stress concentration in the steep slope section of the dam is found out. |
