江门市城区场地土层特征

通过统计地震小区划及一些单体工程场地地震安全性评价工程所积累的资料，对江门市城区各种土类的剪切波速进行了回归分析，得到各类土剪切波速随深度变化的统计规律，并进一步分析了场地土层其它特征，如各类土层的组合模式、厚度以及地面脉动分布特征等，最后给出了建筑场地类别的分区。

Features of site soil layers in Jiangmen city area

Based on the statistical data of the engineering sites in seismic intensity microregion-aliza- tion and seismic safety assessments, the relationship of the variation of shear wave velocities of various types soil layers with the depth in Jiangmen city have been analyzed in this paper. The features of the combined types, thickness and distribution of ground pulsation and so on have been discussed. Finally, the architectural-site types zoning in the city are given.
