摘要/Abstract

摘要： 表土层参数对地震场地响应有重要影响, 通过H/V谱比法和折射微动(REMI)方法确定场地表土层厚度和速度结构等有实际意义。 REMI方法采用常规折射地震采集设备, 利用自然震动作为源, 通过地震波场τ-p变换和傅立叶变换, 将地震记录从时空域变换到慢度-频率域提取频散曲线, 不同于主动源面波勘探, 被动源面波勘探能获得更大深度的土层结构。

Abstract: Soil parameters have an important impact on the response to earthquake damage, H/V spectral ratio and the refraction microtremor (REMI) methods are of practical significance to determine soil thickness and velocity structure of the site. The REMI method acquires data by the conventional refraction seismic equipment, and makes use of ambient seismic field as the source. The transformation from the time-space domain to the slowness-frequency domain will be carried out in the REMI method to extract the dispersion curve by means of the tau-p transform and the Fourier transform. Different from surface wave exploration of active source, the soil structure will be achieved in the greater depth by the dispersion curves inversion.

Key words: Soil parameters, H/V spectral ratio, REMI, Dispersion curves inversion
