摘要

根据江苏华电句容发电一期2×1000 MW发电机组场地情况

布设了三角形嵌套和同心圆台阵进行微振动观测

采用空间自相关法计算频散曲线

并用剥层法反演得到该工程场地浅部的S波速度结构。反演结果与钻孔探测结果吻合较好

表明用微振动台阵记录反演浅部地壳S波速度结构在工程上是可行的。该方法具有不需要人工源

对避开噪声要求不苛刻、成本低且精度可满足工程要求等优点

故有良好的应用前景。

Abstract

On the site conditions of the first period of 2×1000 MW electric generating set of China Huaneng Electric Power at Jurong

Jiangsu province

we designed triangular and concentrically circular arrays for the observation of microtremors;the phase velocities of surface wave were determined by the spatial autocorrelation method（SPAC）

and the S-wave velocity structure of shallow stratum was identified with the stripping method.The consistent result of the inversion with bore-hole shows that this method has following advantages: no requirement of artificial sources

no avoidance of noise pollution

cheap cost of the exploration

and satisfactory precision for engineering;so it has prospective application.
