摘要
介绍响洪甸水库混凝土重力坝通过大坝保温措施前后的坝体应力状态。通过大坝保温,降低拱坝的温度荷载。根据大坝观测资料显示,大坝现有结构性贯穿裂缝均有闭合趋势,说明坝体保温后坝体应力状态大大改善,保温加固效果良好,保证了大坝的安全可靠运行。
The paper gives a presentation of the stress state of the dam body before and after taking the dam heat preservation measures for the Xianghongdian reservoir concrete gravity arch dam .The dam heat pres-ervation reduces the temperature load of the arch dam .T he dam observation data indicate that all the exist-ing structural through cracks in the dam trend to closing ,which means that the dam stress state after tak-ing the heat preservation measures has been greatly improved and the dam has been well reinforced by the heat preservation ,thus ensuring the safe and reliable operation of the dam .
