摘要

In order to study the overall deformation of geotechnical model conveniently,the worksite of landslide bridge foundation reinforced by the front and rear row anti-slide piles in Chenglan railway was taken as an example.On the basis of shaking tabe test of a 1/40 reduced scale model,the landslide deformation caused by vibration waves was monitored through burying self-made phosphor bronze strips in soil.Combined with the horizontal and vertical coordinates of the bending strain points on the phosphor bronze strips,the digital matrix was converted by applying Renka Cline random matrix generation method,and the two-dimensional contour plots were drawn based on it.The results showed that the two-dimensional contour plots reflected the basic law of landslide deformation reasonably,and it revealed the evolution process of landslide deformation and failure.The research conclusions were consistent with the test phenomenon,which met the basic requirements of overall deformation analysis of landslide model.This proposed method can monitor multiple cross sections and was practical for model test.
