三峡大坝左厂14号坝段安全监测资料分析

Safety Monitoring Data Analysis for Dam Block 14 of Three Gorges Left-bank Hydropower Station

三峡大坝左厂14号坝段及其基础是三峡大坝安全监测系统选择的关键部位。通过监测成果对运行期的左厂14号坝段及其基础工作性态进行了全面分析。监测结果表明:坝体及基础变形稳定,防渗效果满足设计要求,坝体应力和温度分布合理。目前建筑物工作状态正常,应力和变形均在设计允许范围内。

Dam block 14 and its foundation of the Three Gorges Left-bank Hydropower Station are chosen as a key part for the safety monitoring system. The work behavior of dam block 14 and its foundation during the operation period is analyzed comprehensively. The monitoring results show that the block and its foundation are stable, the effect of water retaining is satisfied, and the distribution of stress and temperature is reasonable. At present, the work behavior of the dam is normal.
