Abstract

Loess is extensively distributed in many parts of the world, including China, the United State and Russia. Based on experimental study of loess obtained from the three countries, the liquefaction potential of loess are investigated. It is found though loess in the three country all have liquefaction potential, their peak ground acceleration of triggering liquefaction and their behavior during liquefaction vary significantly. Further study of microstructure of loess reveals that the microstructure of the loess in the three countries differs each other in many ways. This factor, combined with the different of gradation, physical index and formation materials, accounts for the different liquefaction behavior of loess in the three countries. Under no circumstance, however, should the liquefaction problem of loess be ignored for its dangerous effects caused by great amount of residual strain during liquefaction.

Comparison of Liquefaction Potential of Loess in China, USA, and Russia

San Diego, California

Loess is extensively distributed in many parts of the world, including China, the United State and Russia. Based on experimental study of loess obtained from the three countries, the liquefaction potential of loess are investigated. It is found though loess in the three country all have liquefaction potential, their peak ground acceleration of triggering liquefaction and their behavior during liquefaction vary significantly. Further study of microstructure of loess reveals that the microstructure of the loess in the three countries differs each other in many ways. This factor, combined with the different of gradation, physical index and formation materials, accounts for the different liquefaction behavior of loess in the three countries. Under no circumstance, however, should the liquefaction problem of loess be ignored for its dangerous effects caused by great amount of residual strain during liquefaction.
