Abstract

The invention relates to a model test device and method for influence of freezing and thawing on deformation of a bedding rock slope. The device comprises a U-shaped slope bench arranged obliquely, jackets are arranged at the bottom of one end, located at a high horizontal end, of the U-shaped slope bench, one end, located at the low horizontal end, of the U-shaped slope bench is movably connected with a buffer platform, and drainage holes are formed in the buffer platform; heating devices are arranged on the periphery of the U-shaped slope bench; tracks are arranged at tops of two side plates of the U-shaped slope bench, multiple sliding seats are arranged on the two tracks, the sliding seats on the two tracks are connected through cross beams in a one-to-one correspondence manner, and multiple dial gages are arranged on the cross beams. The problems that an existing device cannot adjust angles of bedding rock slopes and cannot simulate the effect of freezing and thawing on the bedding rock slope and the like can be effectively solved, and the model test device has the advantages of being convenient to operate, direct in monitoring and the like and has great significance in guiding stability evaluation and treatment of the bedding rock slope in the cold region.

Description

technical field [0001] The invention relates to a model test device and method for the effect of freezing and thawing on the deformation of bedding rock slopes, belonging to the field of geological engineering, in particular to a test method for the effect of freezing and thawing cycles on the deformation of bedding rock slopes, which is suitable for analysis Research on deformation and failure mechanism and stability of bedding rock slopes in cold regions of my country. Background technique [0002] The stability of bedding rock slope is one of the common engineering geological problems in the process of railway construction in mountainous areas, and it is also one of the important issues that railway construction personnel pay close attention to. In northern China, due to the long period of railway construction, the excavated bedding rock slopes often have to go through repeated freezing and thawing. It is complex, and there is no similar experience in slope engineering de...
