基岩劣化对进水塔结构整体失稳影响研究

Research on bedrock degradation effect on stability of the intake tower

基于ABAQUS有限元软件并采用时程分析方法,对三种塔背基岩劣化模型进行数值模拟,计算结果表明随着岩石劣化程度增加,塔体稳定性逐渐削弱,塑性区逐渐增加,塔体及基岩应力也逐渐增大。

Based on ABAQUS software, time history method is used to analysis structure mechanical characteristics with three bedrock degradation model. The numerical simulation results show that with the increase of the rock degradation, stability of tower body gradually weakened and the plastic zone increases gradually, tower body and bedrock increases gradually.
