项目摘要

It is reasonable to design a structural system on an integrated consideration of source, wave propagation path, local site effects, and structure. This study intends to present the ground motion model based on wave propagation theory and source dynamics for seismic design. In this modeling, it needs to present the physical laws which can describe essentially wave propagation from source to site and source process on the fault surface. In relation to this problem, the site amplification characteristics related to the geological properties and topographical conditions of surface and subsurface soil layrs are clarified through the study of seismic response of three-dimensional alluvial deposit with irregularities for incident wave motion from a point source. The source model for the rupture process on the fault surface is expressed by the simple function. According to the above physical laws in modeling, the ground motion model is presented by the Green's function of the soil ground from source to site and the simple source function. The basic formation of wave form function and spectral characteristics, and the site amplification characteristics of wave motions have been presented through the variation of the key parameters of the ground motion model.The effectiveness of this model is verified through the post prediction test against the ground motions of the Off East Coast of Chibaken Prefecture Earthquake (1987) and Hyogo-ken Nanbu Earthquake (1995) . The prediction tests show that the ground motion model agrees well in the wave form functions and response spectra of observed earthquakes. The pertinent ground motion model based on wave propagation theory and source dynamics would present useful information and data for more reasonable seismic design of a structural system.
综合考虑震源、波的传播路径、局部场地效应和结构等因素进行结构体系设计是合理的。本研究以地震波传播理论及震源动力学为基础,提出一个适用于抗震设计的地震动模型。在这种模拟中,需要给出能够从本质上描述波从震源到场地的传播以及震源在断层面上的过程的物理规律。针对这一问题,通过对点源入射波作用下三维不规则冲积存款层地震反应的研究,阐明了与地表和地下土层的地质性质和地形条件有关的场地放大特性。断层面破裂过程的震源模型用简单函数表示。根据上述建模物理规律,采用场地土的绿色函数和简单源函数建立地震动模型。通过地震动模型关键参数的变化,给出了地震动的波形函数和谱特征的基本构成以及场地放大特性,并通过对1987年千叶县东海岸近海地震和1995年兵库县南部地震地震动的事后预测检验,验证了该模型的有效性。预测试验表明,地震动模型与实测地震的波形函数和反应谱吻合较好。基于地震波传播理论和震源动力学的地震动模型将为结构体系的合理抗震设计提供有用的信息和数据。
