摘　　要：近年来,中国新能源项目迅速发展,尤其是在戈壁、荒漠地区大力发展风电、光电项目,具有重大的经济效益、生态环境效益及社会效益,而戈壁、荒漠地区盐渍土分布较为广泛,对工程建设影响较大。结合马鬃山地区项目建设中遇到的盐渍土的特点,通过钻探、原位测试及室内试验等工作,查明了该地区盐渍土的工程地质特性,分析了盐渍土的空间分布规律、气候特征、溶陷性、盐胀性及腐蚀性等物理力学性质,提出了针对工程合理的基础埋置深度,并探讨了盐渍土地基的工程处理措施。In recent years, China’s new energy projects have developed rapidly, especially in the gobi and desert areas. Vigorously develop wind power and photoelectric projects, which have great economic, ecological, environmental and social benefits. The saline soil is widely distributed in the gobi and desert areas which has great influence on engineering construction. Based on the characteristics of saline soil encountered in the project construction in Mazongshan Area, the engineering geological characteristics of saline soil in this area are found out through drilling, in-situ test and laboratory test. In this paper, the spatial distribution law, climate characteristics, physical and mechanical properties of saline soil, such as solubility, salt swelling and corrosiveness, are analyzed, and the reasonable foundation burial depth for engineering is put forward. The reasonable foundation burial depth for the project is put forward and the engineering treatment measures of saline soil foundation are discussed.
