摘要
上海外高桥电厂是我国目前单机容量最大的火力发电厂 ,两条取水隧道是二期工程的一个重要项目 ,但由于其所处地理位置的影响 ,使得设计上取水隧道之间距离较小 ,施工过程中必须进行同步监测。文中详细介绍了监测方案的实施过程 ,分析了隧道内力、隧道断面收敛变形、接触压力等随工程施工的变化规律 ,保证了取水隧道工程施工的顺利进行。
The Waigaoqiao electric power plant in Shanghai is a large fuel electric plant with the largest at present in China electric generator. There are two intake tunnels in the second phase of construction, due to that these two tunnels have been designed too close, a simultaneous monitoring for both tunnels is necessary. In this paper, the full process of the monitoring is introduced and the monitoring data such as the internal force of the tunnel, convergence of tunnel cross section are analyzed to ensure the safety of the construction.
