摘要
小湾水电站工程属大(1)型一等工程,永久性主要水工建筑物为一级建筑物。该工程为混凝土双曲拱坝,拱坝高294.5m,建成后将形成149.14×108m3的水库,总水推力约181000k N。坝顶表观点监测成果显示巨大的水推力作用是致使拱坝产生平面位移变形的主要原因,水位的上升或下降很大程度上影响拱坝的变形规律和大小。因此,本文利用坝顶表观点实测资料,对小湾高拱坝坝顶平面变形的规律、量级进行了深入的研究。
Xiaowan Hydropower Station is a large-scale project with first class,and permanent major hydraulic structures are first class building. This project is concrete double arch with the height up to 294.5m and capacity of 149.14×10^8m^3,and the total hydraulic thrust wil be about 181000kN. The results of monitoring the surface points on top of hydropower show that the huge water thrust is the main causes of plane deformation,while the rise or decline of water level widely influence the law of hydropower plane deformation and value. Therefore,this article has made a further study on the law of plane deformation and order on the basis of the measured data of surface points on top of the Xiaowan hydropower.
