Abstract
Settlement or hardsetting of upland field following to irrigation has been observed in recently developed upland fields in aerial deposit area of Loess Plateau, Northwest China When irrigationiwater was infiltrate into the soil, skeleton of the soil was collapsed instantaneously. This phenomenon is called collapse settlement, which is different to consolidation in soil mechanics. Presenting study used soil ccre and measured stress, strain during applying water subsequent to loading. To explain relations between stress and strain as a function of time, a rheological model was proposed. According to spectrum analysis of generalized Voigt model, the model consisted of a series of one spring. which represents instant large strain and two Voigt elements, which shows delayed compression strain, could explain collapse settlenent of the Loess soiL Proposed model could also explain the collapse settlement characteristics of the Loess soil.
