摘要

多通道表面波分析(MASW)技术越来越多地用于识别浅层地质构造和估计岩土参数，如横波速度、层密度、层厚度、剪切模量、估计纵波速度和估计泊松比。在波兰南部的两个石灰石采石场进行了MASW调查。实验区的特点是地质构造简单:固结的三叠纪石灰岩。测量轮廓被排列成一个有形状的六角星。对于每条测量线，分别使用间距为2米(沉积物1)和3米(沉积物2)的12个检波器。该研究允许比较研究岩体中主要裂缝系统的纵波和横波速度变化。

Application of Multichannel Analysis of Surface Waves to S-Phase Wave Anisotropy Estimation

The Multichannel Analysis of Surface Waves (MASW) is an increasingly used technique for recognition of a shallow geological structure and estimation of geotechnical parameters, e.g., S-wave velocity, layer density, layer thickness, shear modulus, estimated P-wave velocity, and estimated Poisson ratio. MASW surveys were carried out in two limestone quarries in the southern part of Poland. The experimental areas are characterised by a simple geological structure: consolidated Triassic limestone. Measurement profiles were arranged as a shapely six-pointed star. For each survey line, 12 geophones with 2-meter (Deposit 1) and 3-meter (Deposit 2) spacing were applied. The research allowed to compare P- and S-wave velocity changes with the main crack systems in the studied rock masses.
