Abstract

The invention relates to a static and dynamic test device for an anchorage structure of a slope in a cold area, as well as an assembly and test method of the static and dynamic test device, is applicable to a static and dynamic characteristic test technology for an anchorage structure of a slope in a cold area, and belongs to the field of slope supports in a cold area. The static and dynamic testdevice for the anchorage structure of the slope in the cold area comprises a test temperature control box, a test model, a data acquisition system, a vibrating table and a double-beam bridge crane; the test model is put in a test model box, and the data acquisition system is connected with the test model through a communication line, for static test under the freeze-thaw action; the test model after the freeze-thaw action is hoisted onto the vibrating table through the double-beam bridge crane; the model box is connected with the vibrating table through a bolt; the data acquisition system is connected with the test model through the communication line for dynamic test under the action of seismic waves. The static and dynamic test device for the anchorage structure of the slope in the coldarea is novel in structure, simple to mount and convenient to operate, and the optimal design and the scientific design of the anchorage structure of the slope in the cold area can be realized throughthe test technology.

Description

technical field [0001] The invention belongs to the field of slope supports in cold regions, and is specifically applied to the static and dynamic characteristic testing technology of slope anchorage structures in cold regions. Background technique [0002] Large-scale man-made engineering activities in cold regions will inevitably carry out earthwork excavation and filling, which will further aggravate the stability of slopes in cold regions. These problems have brought significant losses to the construction and operation of projects in cold regions. According to statistics, from 2008 to 2010, there were about 50,000 landslides caused by seasonal freezing and thawing, and the direct economic loss was as high as one billion yuan. Landslide damage has gradually increased and has become a major threat to road safety operations. During the operation period of the Harbin-Tongjiang Expressway Harbin-Jia section, a large number of side slopes freeze-thaw and slide every spring, w...
