【摘要】 因拱坝坝后电梯井结构自身的特殊性,其应力沿高度变化规律与一般电梯井结构不同,目前大部分学者研究拱坝坝后电梯井时,对其内部结构进行了简化。采用ANSYS有限元软件分析电梯井无内部结构与增加内部结构在正常与地震工况下应力沿自身高度的变化规律。结果表明:当电梯井结构在正常工况和地震工况时,电梯井位于坝体内部结构主要为压应力,与坝体连接处拉应力较大,拉应力值沿电梯井高度逐渐降低。当电梯井模拟增加内部结构时,电梯井位于坝体内部结构压应力增加,与坝体连接处拉应力值降低。研究结果可为拱坝坝后电梯井设计提供参考。

【Abstract】 Due to the particularity structure of the elevator shaft downstream the arch dam,the variation law of the stress along the height is different from that of the general elevator shaft. At present,most studies simplified the internal structure of the elevator shaft downstream the arch dam. This study used the ANSYS finite element software to analyze the variation of the internal structure of the elevator shaft without increasing the internal structure and increasing the internal structure under normal and seismic conditions. The results showed that: when the structure of the elevator shaft is under normal working conditions and seismic conditions,the internal structure of the elevator shaft is mainly compressive stress,and the tensile stress at the joint with the dam is large,and the tensile stress value gradually decreases along the height of the elevator shaft. When the elevator shaft is simulated to increase the internal structure,the compressive stress of the elevator shaft increased in the internal structure of the dam,and the tensile stress value at the joint with the dam reduced. This study provides reference for the design of the elevator shaft downstream the arch dam.
