Abstract

The moisture migration caused by freeze-thaw cycle is the main reason for the instability of seasonal frozen soil slope in western Sichuan Province. It is an important means to master the rule of water migration by studying the spatiotemporal variation characteristics of permeability coefficient of slope soil. In view of the spatiotemporal variation of permeability coefficient of seasonal frozen soil slope under the action of freeze-thaw cycle, permafrost permeability coefficient tests were conducted on a self-developed device using the coarse-grained soil sample from a slope in Xinduqiao area of western Sichuan Province. The test soil columns with different initial moisture contents, fine particle contents and dry densities were prepared with the osmotic solution of 30% ethylene glycol, and then placed into the low constant temperature box for more than 12 h freezing treatment. The permafrost permeability coefficient tests under different freeze-thaw cycles were then carried out and variations of the permafrost permeability coefficient was analyzed. On this basis, combined with the on-site monitoring data of water content of slope in freeze-thaw period, the spatiotemporal variations of permeability coefficient were analyzed. Experimental results show as follows: with the increase of initial water content and dry density, the open porosity and permeability coefficient of frozen soil decrease. The permeability coefficient of frozen soil decreases with an increase in the fine particle content. When the content of fine particle content is more than 20%, the permeability coefficient of frozen soil decreases slightly. The number of freeze-thaw cycles has an inhibitory effect on the permafrost permeability; however, when the number of cycles is more than 3, the effect of freeze-thaw on the permeability of frozen soil is not significant. Within 1 m frozen depth of seasonal frozen soil slope, the permeability coefficient decreases with the increase of depth; in addition, the permafrost permeability coefficient decreases from November to January, and increases from January to March.
