高拱坝施工期温度徐变应力分析

Thermal and Creep Stresses Analysis of High Arch Dam Construction

在大体积混凝土结构中,温度变化对结构的应力状态具有重要影响,特别是对高拱坝来说,温度荷载是拱坝的主要荷载之一.在对坝体进行应力分析计算时,应掌握温度的变化规律,充分考虑水温、气温等影响因素,本文同时考虑了徐变的影响,运用到工程实际,证明了该方法的正确性.

In mass concrete structures, the temperature change is of importance to stress state of structurest especially for high arch dam thermal load is one of the main loads. The impacts on thermal stress should be calculated considering water temperature and air temperature, etc. The authors also thought of the influence of creep; and it is applied to engineering practice. The results show that the method is reasonable.
