| 摘 要： | 随着我国水电站装机巨型化，隧洞大型化的发展，特大断面隧洞的出现使其施工面临严峻的考验。隧洞作为水电站的关键设施，对其施工导流、泄洪起着尤为重要的作用。利用ANSYS对大型隧洞开挖进行数值模拟，以了解大型隧洞的位移场分布，选择合适的开挖方案。对保障施工安全、加快施工进度均具有十分重要的意义。

| Abstract: | Following the development of hydropower station with giant hydro generator unit and large sized tunnel in China, the occurrence of tunnel with super large sized cross section makes its construction facing with an austere challenge. As one of the key facilities of a hydropower station, tunnel places an important role in the construction diversion and flood discharge of it. An ANSYS based numerical simulation is made on the excavation of large sized tunnel herein, so as to make sure of the distribution of the displacement field of a large sized tunnel and select a relevant appropriate excavation scheme. This has a very important significance for ensuring construction safety and speeding up construction progress. |
