Abstract

The invention discloses a rock blasting super dynamic strain field monitoring and analyzing system which can well obtain an experiment effect of a dynamic fracture mechanics experiment under the load of blasting the natural rock. The system comprises a loading unit, a high-speed high-resolution image pickup unit, a light source unit, a synchronization unit and a digital image analysis unit, wherein the loading unit is used for carrying out blast loading on a natural rock test block and generating a super dynamic strain field in the test block; the high-speed high-resolution image pickup unit is used for carrying out alternative shooting or simultaneous shooting on the dynamic fracture process of the natural rock test block by at least two digital imaging subunits so as to obtain crack propagation images at different moments; the light source unit is used for providing illumination or reinforcing illumination light for the natural rock test block; the synchronization unit is used for carrying out synchronous control on actions of the loading unit, the high-speed high-resolution image pickup unit and the light source unit; and the digital image analysis unit is used for analyzing images shot by the image pickup unit. The system is suitable for performing the dynamic fracture mechanics experiment under the load of blasting the natural rock.

Description

technical field [0001] The invention relates to the technical field of related dynamic fracture mechanics experiments of materials, in particular to an ultra-dynamic strain field monitoring and analysis system under the action of rock blasting. Background technique [0002] At present, domestic and foreign laboratories mainly use dynamic photoelastic experiment system, digital camera dynamic caustic experiment system, ultra-dynamic strain acquisition instrument and so on to study the dynamic failure mechanism of rock under the action of blasting load in laboratories at home and abroad. However, most of the currently established experimental systems are only tested on model materials, and the conclusions obtained are still somewhat different from those of real natural rocks. How to carry out relevant dynamic fracture mechanics experiments on natural and real rocks under blasting loads, and analyze the dynamic strain field in the plane of the rock test block or the strain fiel...
