Abstract

The invention discloses a landslide model horizontal acceleration amplification coefficient testing method, which comprises the following steps: S1, designing and manufacturing a detachable ship-shaped protection shell according to a horizontal accelerometer ship-shaped protection device manufacturing method, and fixing a horizontal accelerometer in a circular protection cover; S2, burying a horizontal accelerometer ship-shaped protection device of a monitoring section according to an acceleration measuring point layout principle, and calculating a horizontal acceleration amplification coefficient of a measuring point after vibration is added; S3, generating a digital matrix by using a RenkaCline algorithm according to a digital matrix generation method based on the measuring point coordinates and the horizontal acceleration amplification coefficient; S4, obtaining a horizontal acceleration amplification coefficient distribution rule of the landslide model according to a horizontal acceleration amplification coefficient two-dimensional equipotential line color graph generation method. The method is used for solving the problems of reliability of a horizontal accelerometer protection device, subjective randomness of measurement point layout, incapability of visually and vividly presenting the distribution condition of a horizontal acceleration amplification coefficient of a monitoring section and the like.

Description

technical field [0001] The invention belongs to the technical field of dynamic testing of rock and soil models, and relates to a method for testing the horizontal acceleration amplification factor of a landslide model. Background technique [0002] In the landslide model dynamic test, the horizontal acceleration amplification factor of rock and soil is an important assessment index, which is used to analyze the dynamic response characteristics of the landslide, to study and judge the potential law and evolution mechanism of soil sliding damage, and to provide reference for the design of seismic reinforcement scheme, Landslide early warning, etc. provide technical reference. [0003] At present, many horizontal accelerometer protective devices in the landslide model are self-made based on experience, and the quality is uneven. There is no corresponding guiding principle for the layout of acceleration measuring points, and there is a certain degree of subjective blindness. Th...
