| 摘 要： | 采用三维振型分解反应谱法分析深圳公明供水调蓄工程进水塔结构的自振特性,研究了正常蓄水位下分别遭遇顺水流向和垂直于水流向地震时进水塔的地震加速度、动位移和动应力响应,并验证进水塔的抗震稳定性。验证结果表明进水塔的变形和强度满足设计要求。为提高进水塔桩基础的水平承载力,建议在垂直于水流方向增加6根桩。

| Abstract: | The natural vibration characteristics of the intake tower of the Shenzhen Gongming Water Supply Project are analyzed with the three-dimensional mode-superposition response spectrum method.The earthquake acceleration,dynamic displacement and dynamic stress of the intake tower at normal water levels during an earthquake along the flow or perpendicular to the flow are examined.Seismic stability of the intake tower is verified.The results indicate that the strength and deformation of the intake tower meet the design requirements.To improve the horizontal bearing capacity of the intake tower pile foundation,it is recommended that six piles are added in the vertical direction of the flow. |
