摘　　要：膨胀土边坡的防护与加固研究一直是岩土工程领域的一项重大课题,由于膨胀土的涨缩性,膨胀土边坡在防护过程中易发生脆性破坏,与刚性防护措施相比,柔性防护更能适应边坡的变形。本文针对膨胀土的特性,提出SNS柔性防护技术,对其防护机理进行了分析,阐述了SNS柔性防护技术在周南高速中的应用技术。Protecting and reinforce of cutting slope of expansive soil has always been an important subject in the field of geotechnicol engineering. Beccuse of the swelling and shrinkaae of expansive soil, compareded with the rigid protective measures foc brittie failure of txpansive soil slope in the process of protection, flexible protection is more suitabie foc slope deformation. In this papeo, according te the characteristics of expansive soil, SNS tlexibie protection technolooy is proposed, and its protection mechanism is analyzed, and the application technolooy of SNS flexible protection technolooz in Zhounan Expossway is expounded.
