浅海重力式海洋平台抗震试验研究
|
摘要
随着西太平洋区域板块边缘地震活动性的逐步增强,浅海重力式海洋平台遭受地震破坏的风险正逐渐加大。本文的主要工作是利用大型振动台,采用1∶25相似比的有机玻璃材料试验模型,施加人工质量,试验研究了带裙板的浅海重力式海洋平台在基底地震动输入下的动力反应及其规律。试验结果显示平台总体抗震性能尚可,平台在双向地震动输入下抗扭能力差,建议予以重点加强。
Along with the seismicity of the west Pacific plate margins being strengthening,the risk of Gravity Platform in Shallow Sea being damaged by earthquake is gradually increasing.This paper main job is to use large vibration table,Organic glass model whose similar-ratio is 1∶25,exerted artificially quality to research on Gravity Platform with skirt board in the basal gravity type ground motion input conditions and the dynamic response of the law.The result of experiment and numerical simulation compared with consistency,,and the results showed that the Platform had better seismic performance,overall seismic performance for earthquake weak link were ends of the columns.
