Device and method for testing allowable normal frost heaving displacement of soil slope protection structure
The invention provides a device and a method for testing allowable normal frost heaving displacement of a soil slope protection structure, and relates to a device and method for testing allowable normal frost heaving displacement. The device and method aim at solving the problem that design, application and popularization of the soil slope protection structure in cold region hydraulic engineering are limited. The protection structure displacement testing device is installed over a soil slope foundation soil uneven frost heaving and thaw collapse deformation simulation device and used for testing displacement of the soil slope protection structure. The method includes the steps that a second lead screw is rotated clockwise, when an annular body on the innermost ring ascends to a set limit position, the second annular body is driven to ascend till the accumulated ascending height reaches preset foundation soil uneven frost heaving deformation, and simulation of frost heaving deformation is completed; the second lead screw is rotated anticlockwise, the annular body resets, and simulation of thaw collapse deformation is completed; and a three-dimensional terrain measurement system is used for testing displacement of the protection structure in the uneven frost heaving and thaw collapse deformation process. The device and method are used for measuring allowable normal frost heaving displacement.
