摘    要:针对江西上犹江水电站大坝闸墩裂缝和检查廊道顶拱的贯穿裂缝,运用温度场和温度应力的有限元方法对施工和运行过程进行模拟计算,在运行期重点考虑夏季泄洪冷击和冬季寒潮对开裂的影响,根据计算结果对裂缝的成因进行分析。计算结果表明,不同时期的温度应力是产生裂缝的主要原因。提出了裂缝处理和预防的建议。

关 键 词:混凝土重力坝  闸墩裂缝  廊道顶拱裂缝  温度应力  仿真计算  上犹江水电站

Abstract:The FEM for temperature field and temperature stress was applied to simulation of cracks going through the pier and arch crest of inspeetion gallery of the dam for Shangyoujiang Hydropower Station during its construction and operation periods. The influences of cool flood discharge in summer and cold wave in winter on cracking during the operation period were focused. According to the result of calculation, the temperature stress in different periods is the main influencing factor for cracking. Finallv. some suggestions for crack orevention and treatment were made.
Keywords:concrete gravity dam  crack in pier  crack in arch crest of gallery  temperature stress  simulative calculation  Shangyoujiang Hydropower Station
