广东省天堂山拱坝蓄水期监测及应力分析

利用施工期预埋的应变计、无应力计、温度计和渗压计等对广东省天堂山拱坝首次蓄水期的坝体应力、温度以及拱座的反力等进行了实测，通过对测试结果的计算和分析，探讨了拱冠梁、拱座和坝体的应力分布及安全性．结果表明，本文所述方法对于监测和分析高拱坝的应力状态和结构安全性是十分有效的．

MONITORING AND STRESS ANALYSIS OF THE TIANTANG MOUNTAIN ARC DAM DURING ITS WATER STORAGE TERM

With many instruments such as strainometers, non_stressometers, thermographers and piezometers fixed up during the period of construction of the Tiantang Mountain Arc Dam in Guangdong province, a great deal of data are measured during the first water storage term, such as the dam's stress, temperature and the stress of base heel. Through the calculation and analysis of monitoring data, the stress distribution and the safety of arc crane, base heel and dam are studied. It is shown that the method introduced in this paper is quite efficient for monitoring and analysing the stress condition and structure safety of high arc dam.
