Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] refer to figure 1 , a dangerous rock vibration characteristic test system with controllable cohesion, including a vibration characteristic detection and processing device for detecting data such as vibration frequency and amplitude of an object; a base embedded with a suction cup electromagnet; Ferromagnetic control box.

[0022] Such as figure 1 As shown, the vibration characteristic detection and processing device includes a three-dimensional laser vibrometer 2 and a data analysis processor 1 . The 3D laser vibrometer 2 adopts the laser vibration measurement technology based on the Doppler principle, which can accurately measure the vibration signal of a long-distance object, including displacement, velocity and acceleration data. The 3D laser vibrometer 2 is placed on a tripod to keep it stable. The influence of the vibration of the instrument itself on th...

Abstract

Disclosed is a crag vibration characteristic testing system with controllable cohesive force. The system comprises a base, a control box which is used for controlling magnetic force of a holding magnet solenoid, and a vibration characteristic detection and processing device for detecting vibration frequency and amplitude data of objects; the base comprises the holding magnet solenoid, a slope board, a slope board clamping groove and a lifting mechanism; the slope board is installed on the slope board clamping groove of which one end is connected to the ground. The other end of the slope board clamping groove is installed on the lifting mechanism for adjusting the slope angle. The solenoid for attracting a magnetic tested sample is installed at the bottom of the slope board clamping groove. The upper portion of the slope board is a primary position where the magnetic tested sample is placed. The solenoid is located under the primary position. The controlled end of the solenoid is connected with the control box. The crag vibration characteristic testing system with the controllable cohesive force is good in stability and high in precision.

Description

technical field [0001] The invention belongs to the field of prevention and control of slope geological disasters in geotechnical engineering, in particular to a vibration characteristic test system of dangerous rock with controllable cohesive force. Background technique [0002] In recent years, with the development of the economy and the construction of various projects, a large number of artificial slopes and natural slopes near roads and residential areas have appeared. While causing irreparable losses to property, it also brings serious hidden dangers to the safety of transportation such as roads and railways. [0003] Affected by the surrounding environment and its own degradation process, dangerous rocks will become unstable and collapse. The key to judging the stability of dangerous rock is to find out the connection state between the target rock mass and the bedrock. Most of the rock blocks that have fallen have insufficient adhesion to the bedrock. Conventional d...
