微动勘探技术在城市轨道交通勘察中的应用
Application of micro tremor technology in urban rail transit survey
摘要
Abstract
Micro tremor, as an exploration method based on natural source, has the advantages of convenient, low cost, envi-ronmental friendly, so its application in the urban rail transit project becomes increasingly extensive. Test and research on micro-tremor were carried out in a pre-stage exploration of Wuhan rail transit site by using S-FLEX high-fidelity wireless 3-D seismic data acquisition system. The micro tremor data was collected through the arrangement of circular array, and the frequency dispersion curve of micro tremor data was extracted by SPAC method to inverse underground media S wave velocity profile. The results of the experiment indicate that the micro tremor is suitable for geological-detection in the complex environment of urban site and the magnetic environment, the data acquisition is convenient and velocity stratification is accuracy and reliable.关键词
