堆石混凝土筑坝技术要推广应用到高坝工程中,其温控问题需要研究。本文结合堆石混凝土坝的材料特性和施工工艺,分析了堆石混凝土坝的温控特点,运用大型结构多场仿真与非线性分析系统软件SAPTIS,对堆石混凝土坝不同温控措施下的温度场和应力场进行了仿真分析,提出了堆石混凝土坝的温控措施,可供同类工程参考。
The problems from the temperature control are necessary to be studied for popularizing and applying the technique of rock-filled concrete dam to the construction of high dam. Combined with the material characteristics and construction technologies of rock-filled concrete dam, the characteristics of the temperature control of the dam is analyzed herein, and then the software of multi-field simulation and nonlinear analysis of large structures--SAPTIS is applied to the simulative analysis on the temperature field and stress field of the rock-filled concrete dam under various temperature control measures, thus the temperature control measures for the rock-filled concrete dam is proposed; which can provide a reference for the similar project concerned.
