Changji Expressway Western Slope section of structure and protective measures

Level surface composition and structure of unstable blocks the formation of sliding failure. Support patterns tend to slope aspect and angle between the rock is small, the use of step excavation; for the medium / steep dip dip slope,[link widoczny dla zalogowanych], slope failure mode of rock slope sliding failure along dimensions, slope stability problem exists. Support Measures for the sliding of the potential volume of bedding and depth, using a long bolt or anchor on the potentially unstable rock reinforcement. (2) Cambrian limestone slope,[link widoczny dla zalogowanych], slope at the top of the problems is the existence of a certain thickness of the entire weathered residual soil,[link widoczny dla zalogowanych], easy to form a shallow slide in the development of dissolved limestone trenches, filling the residual gap solution earth,[link widoczny dla zalogowanych], easy to form a mud flow. Appropriate support measures to slow down the slope to the top of all weathered residual soil slope, the use of grid beam Slope Stabilization, clear gray karst holes, gap filling solution residual soil. (3) Proterozoic Banxi mainly sandy slate dump slope deformation based, support measures for the 1-3 slope by cable anchors, the other with bolt reinforcement. (4) For loose soil composed of layers or rock mass slope, mainly based loosely sliding layer, slope protection should be taken to anchor the grid beam, or by retaining wall, the other using grid beam + anchor Rod and Slope Stabilization processing; for significant deformation and large sliding slope, using gravity retaining wall or pile Sliding of reinforcement. The structure of the type used with the slope deformation and failure modes and adapt to the slope protection program, in Changji Western Slope section of harnessing project achieved good results, for other linear project design and construction of slope protection reference.
