三维模型实验相似准则

THE SIMILITUDE PRINCIPLE FOR THE 3-D SEISMIC SCALE-MODEL INVESTIGATION

本文依照相似方法的基本原理,从模型相似必须遵守的基本条件出发,提出了三维地震模型实验应遵循的基本相似准则。 三维地震模型实验是模拟野外三维地震勘探方法、技术的一种缩小了的模型。为了正确地模拟地震波在地下传播的物理过程和现象,必须遵守下述条件:

In this paper, from the fundamental principle of the similitude method and the basic condition between a model and an original, the guiding principle is presented for the 3-D seismic scale-model inrestigation.It not only introduces simple simulative scales of 3-D seismic models,such as time, space density and velocity, but also discusses simulative scales of some important physical parameters, such as module of elasticity,coefficient of viscosity, coefficient of attenuation, waveform, frequence spectrum and point source, providing references for scientists in designing and studying 3-D seismic models.
