摘要

简述了稳态及瞬态瑞利波测试系统和瑞利波相速度频散曲线的求取原理，指明了瞬态SASW法所得的频散曲线与稳态法结果等价的理论前提，提出了一种通过控制测试过程来改善SASW法测试效果的优化相干函数方法。

Abstract

The testing systems of Rayleigh wave both in steady-state and transient-state and the calculating principle of dispersion curves of phase velocity of Rayleigh wave are simply described first. Then

the theoretic presupposition

on which the dispersion curve from SASW method may be equivalent with the result from steady-state method

is pointed out. An optimized coherence-function method

by which the testing effect of SASW method can be improved by means of testing procedure control

is proposed at last.
