Abstract

Abstract

The mechanical properties of saline soil are one of the hotspots in geotechnical engineering research. Based on a series of direct shear tests， the shear mechanical properties of silty sulfate saline soil under different vertical pressures， soil moisture contents， and salt contents were studied. The research results show that there is a critical value （dissolution saturation） for the influence of water-salt action on the shear strength of silty saline soil. Before reaching the dissolution saturation， an increase in salt content will lead to an enhancement of the lubricating properties of the salt solution. Thus， the shear strength and shear strength parameters， such as cohesion and internal friction angle of sandy saline soil， all decrease with the increase of salt content. When the dissolution saturation is reached， the salt crystallization phenomenon intensifies with the increase of salt content. The shear strength and shear strength parameters， such as cohesion and internal friction angle of sandy saline soil， all increase with the increase of salt content. Based on the influence mechanism of the mechanical properties of saline soil， a new engineering countermeasure for the prevention and control of saline soil with geotextile bags was proposed.
- silty sulfate saline soil,
- shear strength,
- impact mechanism,
- prevention countermeasure
