景洪水电站水力式升船机塔楼结构性态分析
|
摘要
针对水力式升船机的受力特点,拟定了其设计工况和主要荷载的取值,在此基础上采用数值计算方法对景洪水力式升船机的塔楼结构性态进行了研究.结果表明,该塔楼结构形式合理,但由于结构较为单薄,其应力状态较为复杂,许多部位出现较大的拉压应力,需要采取一定的工程措施来改善这些部位的应力状况.
Based on stress characteristics of the hydraulic ship lift,design conditions and main load values of the tower were determined.Then,the numerical calculation method was used to study the behavior of the tower structure of hydraulic ship lift for Jinghong Hydropower Station.The results show that the structural style of the tower is appropriate but its stress state is complex,and there are larger tension stress and compression stress at some locations.Some engineering measures are needed to improve the stress state at these locations.
