Abstract: The methods for side-slope protection along Lan-Xiao Highway can be divided into two categories.The first one is focused on eliminating or reducing stress factors which negatively effect the side slope stability.The other one is aimed to reduce the thrust potential or enhance the anti-slide.For a concrete side-slope,the process of control is according to the principle of “conceptual design and information operation”,as well as optimum design and comprehensive treatment.The side-slope protection methods used in sections K10 and K12 are summarized in this paper.In addition,a new type SNS protective wire mesh is briefly introduced.
