Calculation of Disturbance Characteristics of Steel Beam in Gate Chamber of Hydropower Station based on Repeated Load Method

文章采用反复荷载方法对水电站闸室钢梁扰动特征进行计算。计算结果表明:反复荷载计算的闸室钢梁屈服弯矩及极限弯矩与室内测定值具有较好的吻合度,可用来分析不同荷载下钢梁扰动强度及抗剪分析。研究成果对于水电站闸室钢梁稳定指标设计具有重要参考价值。

The disturbance characteristics of steel beam in gate chamber of hydropower station are calculated in this paper by using the method of repeated load.The results show that the yield bending moment and ultimate bending moment calculated by repeated loads are in good agreement with the measured values in laboratory,which can be used to analyze the disturbance strength and shear strength of steel beams under different loads.The research results have important reference value for the design of steel beam stability index of hydropower station lock chamber.
