Abstract

Abstract

Loess hydrocompaction has been discussed for a long time.During the 1960s ~ 1980s, with the application of SEM and mineral analysis, the micro-structure theory of loess hydrocompaction was developed and improved, but it has rarely been used in engineering numerical analysis because it failed to supply related force stress parameters.Progress in soil engineering and soil mechanics makes it possible to find a new way to study the loess hydrocompaction.This paper discusses mechanical attribute of loess hydrocompaction and proposes a concept of generalized loess hydrocompaction.An analysis is made on some issues about study on hydrocompaction from the viewpoint of unsaturated soil mechanics, and finally a case study is given.
- loess hydrocompaction mechanisms /
- micro-structure /
