格里桥水电站大坝温控反馈设计初探

Design of Feedback Temperature Control for Dam of Geliqiao Hydropower Station

碾压混凝土坝一般在可研和招标阶段已完成了温控仿真分析,但目前在施工阶段结合现场实际情况进行温控反馈分析的较少。依托格里桥水电站工程,笔者对碾压混凝土坝进行了初步的温控反馈设计研究,研究从大坝温控反馈设计原理、大坝温控仿真计算成果及分析、大坝温控反馈计算成果及分析等几方面,对格里桥水电站大坝温控反馈设计成果进行了复核及与实际监测资料的对比分析,及时为工程提供了有针对性和参考性较强的建议,提高了工程温控设计质量。

Usually the simulation analysis on temperature control for the RCC dam has completed at the stages in feasibility study and invitation to bid.There are very few cases of analyzing the feedback temperature control with field reality testing data.The author preliminary studies on the design of feedback temperature control for the RCC dam.The article contains the fundamentals of feedback design,the result and analysis of simulation calculation,result and analysis of feedback calculation,and so on.Meanwhile,the design results of feedback temperature control for the dam are rechecking and analyzing compared with the actual monitoring data.The article timely provides a directly and referential suggestion for this project,and improves its design quality of temperature control.
