摘要
本文简要介绍了微动勘探法的进展和基本原理,以圆形台阵和嵌套式三角形台阵为主介绍了微动勘探的台阵布设方式和工作方法,通过试验研究了台阵中台站的数量、台阵的规模、台阵中拾震器的自然频率及采样时长等几个因素对探测结果的影响,总结了浅部地层微动勘探的关键参数设置原则。
The progress and basic principle of micro-tremor exploration is briefly introduced. Based on the circular array and nested triangular array,the array layout and working methods of micro-tremor exploration are introduced. The influence of several factors such as the numbers of stations,the size of the array,the natural frequency of the detector in the array and the length of sampling time is studied. The setting principle of key parameter of the shallow stratum micro-tremor exploration is summarized.
