CT Analysis of Meso-Structure Changes in Rock Salt with Brine Corrosion

Article Preview

Abstract:

The roadbed base of railway in Qarhan Salt Lake area entirely consists of brine saturated rock salt formations. However, low salinity brine would cause corrosion for roadbed and the stability of rock salt roadbed would be directly affected. In this paper, physical and mechanical properties of brine-dissolved rock salt have been tudied, as well as Computer Tomography was used to scan and analyze the meso-structural changes in rock salt before and after corrosion. The results show that density of rock salt would be changed obviously in the process of corrosion.The deriving or closing of meso-fissures in rock salt could been found with rock salt immigrating and corrosion damage.
