软岩地基进水塔结构静动力三维有限元分析

Static and Dynamic Three-dimensional Finite Element Analysis of Intake Tower Structure on Soft Rock Foundation

某水利工程泄洪洞进水塔为直立的悬臂结构,在多种荷载作用下其稳定性和结构安全相对较差。采用有限元方法,计算塔身在静动力状况下的抗倾、抗滑稳定情况及塔身各部位的应力分布,对其进行稳定及结构应力分析研究。结果显示,该工程进水塔结构设计合理,有良好的稳定性和安全性,可为进水塔的设计及类似工程建设提供参考依据。

The intake tower of flood discharge tunnel in a water conservancy project is an upright cantilever structure,and its stability and structural safety are relatively poor under various loads.The finite element method is used to calculate the anti-overturning and anti-sliding stability of the tower body under static and dynamic conditions and the stress distribution of each part of the tower body,and the stability and structural stress analysis are carried out.The results show that the design of the intake tower structure of the project is reasonable,with good stability and safety,which can provide reference for the design of the intake tower and the construction of similar projects.
