摘要
天花板水电站拱坝建基面高程的确定在设计的不同阶段都是设计研究的关键问题。在施工过程中,随着坝肩、坝基不断开挖的揭露和岩体试验,对坝基地质情况会有新的认识和研究。天花板拱坝施工中,设计单位为进一步节省工程投资和缩短工期,对拱坝建基面能否抬高开展了大量的坝基试验测试和坝体应力计算等分析论证工作,最终将建基面抬高了6.0 m,不但取得了较好的工程效益,还积累了拱坝设计的一些经验。
The elevation of dam-foundation interface of Tianhuaban Arch Dam is always a key issue in different design stages. With the excavation of dam foundation and abutment and the rock tests, there is new knowledge on the geological condition of foundation. In the construction of Dam, the foundation tests and stress calculations of dam are carried out to decide whether the elevation of dam-foundation interface is raised for further saving investments and shortening construction period. The dam-foundation interface is finally lifted by 6.0 m. The adjustment of dam-foundation interface not only achieves better benefits, but also accumulates some experiences in arch dam design.
