含氯盐遗址土盐渍风蚀效应试验研究

In this paper, saline wind erosion, which is defined as the salinized deterioration of the rock-mass and soil-body exacerbating their loss of wind erosion, is studied as a universal damage effect in nature, and has a particularly great significance on the earthen sites of the arid area in northwest China. With the effect of this, the growth and development of the undercutting and recessed footing seriously threatens the overall stability of the sites. In order to scientifically formulate targeted and effective protective measures, study of its failure mechanism has become a key issue to be solved. This paper is based on laboratory experiments, and by using remodeling samples of site soil that is desalted and mixed with chlorine of different content for acoustic testing and wind erosion experiments, it gives a preliminary analysis of the mechanism for the saline deterioration and wind erosion loss of the site soil, and all these draw a conclusion that during the process of the structure degradation and soil loss of saline site soil samples, the salt content and wet and dry cycles serve important functions as inertial factor and outer help power respectively, which provides a theoretical basis for the future study of such diseases of the sites and for the proposal of appropriate measures for its prevention and treatment.
