Research on the Protection Technology of Anchor Lattice Beam for Highway Subgrade Slope
Taking a highway engineering in Shandong province as an example,the slope stability is analyzed through the slope joint stereographic projection,the slope stability coefficients under three kinds of working conditions are calculated,the technical parameters of the protection slope of the anchor lattice beam are determined,and finally the displacement and shear stress distribution of the slope before and after the addition of the anchor lattice beam are calculated by using the finite element software.The research results show that:the intersection of the slope joint projection is on the other side of the slope projection arc and it is located in the slope of the weak structural plane,and some rock masses on the slope will be in an unstable state under the extreme climate or earthquake action.After the addition of the protection slope of the anchor lattice beam,the slope stress is greatly improved,the displacement and shear stress concentration of the lower part of the slope are significantly reduced,and the slope stability is improved.
