摘要
国内历次震害表明,不同埋深的构筑物其动力响应是不同的,因此不能将有理深的结构示为地面结构来进行动力分析。本文用Baranov-Novak分析方法,对给排水工程中常见的刚度较大的理五构筑物进行了动力分析,考虑了理深的影响和土与结构的相互作用,结果反映了实际震害的情况,并进而提供了与埋深相关的惯性力折减系数及其应用方法可供设计参考应用。
Many domestic earthquake damages show that stracture with different emhedded depth had different behaviour.So the dynamic analysis for emhedded strvcture should be distinguished from that of no embedded depth. Uisng Baranov-Novak method, the seismic analysis is carried out for embeddel structure in sewerage and water supply engineering considering the interaction between soil and structure. Analytical results indicate the practical situation. This paper also gives out the force decreasing factors and its using method to be available for design.
