【摘要】 拱坝整体结构随大坝浇筑、封拱不断推进而逐渐形成的,坝体结构形式在施工过程中是变化的.正因为结构形式是变化的,在浇筑、封拱过程中坝体承受的荷载形成的力学效应也是不断变化的.本文基于施工期拱坝结构的变化,着重研究了拱坝自重荷载与温度荷载在施工期加载过程,为进一步研究拱坝施工期力学性质提供理论支持.更多还原

【Abstract】 The integral structure of arch dam will be gradually formed with the process of construction and arch closure.As a result,the structure in the period of construction often changes from time to time and the loads of arch dam also change as well.Based on the changing process of structure of arch dam,the process of loading of gravity and temperature of arch dam in construction period are studied emphatically.The studied result will provide theoretical support for further study of mechanical character of arch dam in construction period.更多还原
