科尔沁风积沙静力特性及强度变形规律研究

Study of the static characteristics and the law of strength-deformation of wind-blown sand in Horqin Shadi

依托内蒙古自治区省际大通道赤峰-通辽支线的修建,结合《科尔沁沙地风积沙路基击实标准及检测方法研究》课题的开展,通过对科尔沁风积沙的CBR值、回弹模量、压缩试验的数据分析,研究科尔沁地区风积沙的静力学特性,即强度-变形特点,以确保风积沙路基具有更好的强度、稳定性。

Based on the construction of Chifeng to Tongliao Expressway of inter - provincial highway within Inner Mongolia, in combination with the research on method for detecting the compactness of wind - blown sand, this paper gives the study results according to the data analysis on the CBR value, resilient modulus, compression test, the static characteristics of the sand in the above area were researched, including the features of stress - strain curve, to ensure the subgrade with wind - blown sand having a better strength, and stability.
