东北太平哨和云峰砼重力坝已分别运行十余年和二十余年，需进行安全检查与评价．本文首先介绍了现场动力试验和自振特性及地震动应力分析结果．对云峰宽缝重力坝进行了抗滑稳定复核，静力和温度应力计算，并研究了基础岩石裂缝、扬压力、上游库区水压力及材料弹模对应力状态的影响。 Pacific Taibin and Yunfeng concrete gravity dam have been operating for more than ten years and more than twenty years, respectively, requiring safety inspection and evaluation. This paper first introduces the field dynamic test and natural vibration characteristics and seismic stress analysis results. The anti-skid stability review, static and thermal stress calculation of Yunfeng wide-gap gravity dam were carried out. The effects of fracture, uplift pressure, water pressure in upstream reservoir and material stress state on material deformation were studied.
