Study on the Microstructure of Loess in Meizoseismal Zone
Study on the Microstructure of Loess in Meizoseismal Zone
摘要
Abstract
In this paper, quantitative study on the microstructure of loess is done based on the study of seismic subsidences of the Yongdeng Ms5.8 earthquake in 1995. Using SEM and image processing techniques, a comparison analysis on the microstructure of loess is done and distribution curves of loess pores are obtained. Based on laser grain analyzer test and trellis structure changes under earthquake effect, the dynamic properties of loess are explained. At the same time, pore distribution of loess from seismic zone and non-seismic zone is compared.The result shows that the pore distribution features of different meizoseismal zones are different, and even that loess at the similar depths bas substantial differences, too.关键词
