清江隔河岩水利枢纽大坝采用上重下拱式组合坝型 ,坝前库水位年变幅较大 ,大坝变形有一定特点。通过建立变形观测资料数据库 ,进行数据可靠性检验和适当的误差处理 ,从定性分析出发 ,给出工程蓄水期和运营阶段的变形性状 ,在此基础上 ,选定关键部位 ,用实测资料建立统计数学模型 ,定量解释、分析大坝工作状态。通过资料分析 ,认为工程结构及基础稳定 ,变形符合一般规律 ,处于正常工作状态。
The Geheyan hydroelectric dam of Qingjiang River adopts the combination of upper heavy arch and lower arch type, and the amplitude of water level in front of the dam is large in a year, and the dam deformation has certain characteristics. Through the establishment of the deformation observation data base, the data reliability test and the appropriate error processing are carried out. Based on the qualitative analysis, the deformation characteristics of the reservoir during the storage period and the operation phase are given. Based on this, the key parts are selected and established with the measured data Statistical mathematical model, quantitative interpretation, analysis of dam status. Through data analysis, that the project structure and foundation of stability, deformation in line with the general law, in normal working condition.
