The propagation velocity of elastic wave with different frequencies in same medium is various,which is called dispersive problem of frequency.This phenomenon can be simply thought as:velocity has function relationship with frequency.The relationship is influenced by the saturability of medium,the stress to medium,and so on.It has been researched systematically on abroad,and an analysis technology was put forward to predict all the velocity’s dispersive of frequency from zero to ultrasonic frequency.In practice,through no way can us well predict the relationship.We need a normalized relationship when we want to compare the seismic wave data with ultrasonic data.In this paper,through the measurement and comparison analysis of ultrasonic velocity and seismic wave velocity on a group of concrete piles,a audiovisual correlation coefficient 1.136 was obtained.When the condition is similar,for example,to concrete pile or the rock with seismic wave velocity of 3000~4200 meters per second,we can use the relationship.So,according to the seismic wave velocity or ultrasonic velocity,the ultrasonic velocity or seismic wave velocity whose measurement may be constrained for some reasons can be estimated.

相同介质中不同频率的弹性波传播速度是有差异的,即频散问题。频散暂且简单的理解为速度是频率的函数。这种关系受许多因素如介质的饱和度、所受应力等的影响。国外在这方面有较系统的研究,并提出了一种预测零频到超声波频率之间全部速度频散的分析技术。但在实际应用中并没有一种很好的办法来估算这种关系。当我们需要把地震波资料和超声波资料作对比时就需要一个归一关系。本文通过对一组混凝土桩同时进行超声波和地震波测试,然后分析对比,得到了一个很直观的对应系数:超声波速/地震波速=1.136。在条件相近的情况下,比如建筑物下一般的混凝土桩或地震波速在3000~4200m/s的岩石,就可以方便的引用这一关系,根据已知的地震波速或超声波速去推测由于条件限制无法测得的超声波速或地震波速。

The general alternating difference scheme with intrinsic parallelism is presented for solving the one-dimensional dispersive problem. The unconditional stability of the constructed scheme is proved. The alternating group explicit scheme constructed before is the special case of the general alternating scheme. And as other special cases, the alternating segment explicit-implicit scheme and the alternating segment Crank-Nicolson scheme are also obtained. Numerical results by the several schemes are given....

对一维色散方程给出了本性并行的一般的交替差分格式,证明了该类格式的绝对稳定性,已有的交替分组显格式(AGE)是该类格式的特例,作为特例,进一步得到交替分段显-隐格式(ASE-Ⅰ)和交替分段Crank-Nicolson格式(ASC-N),数值实验比较了这几个格式数值解的精确性。
