Abstract: To understand the tensile strength behavior of chlorine saline soil,the axial tensile test of chorine saline soil specimens were carried out,using chlorine soil of Luoyang loess disposed indoors as an object of study.The influence of dry density,initial water content,salt content on the tensile strength of chlorine saline soil were investigated.The test result indicated that the logarithmic relation between tensile stregth and water ratio under the same salt content and dry density are obtained;the tensile strength of samples increased with the increase of dry density;pulling stress decreased first and then increased with the increase of salt content when water content was less than 15%.The salt content of the inflexion was 8%.When the water content was more than 15%,the tensile strength decreased with the increase of salt content,while tension strain has an opposite changing law.With the increase of water content, the failure tensile stress decreased while the tension strain increased under the same salt content.
