一种岩石爆破超动态应变场监测系统
摘要：
本实用新型公开一种岩石爆破超动态应变场监测系统，能够较好地获得对天然岩石进行爆破载荷下的动态断裂力学实验的实验效果。所述系统包括：加载单元，用于对天然岩石试块进行爆炸加载，在试块中产生超动态应变场；摄像单元，用于通过至少两个数码成像子单元对天然岩石试块中的动态断裂过程进行交替拍照或同时拍照，获得不同时刻的裂纹扩展图像；光源单元，用于为所述天然岩石试块提供照明或补强照明光线；同步单元，用于对所述加载单元、摄像单元、光源单元的动作进行同步控制。本实用新型适用于对天然岩石进行爆炸载荷下的动态断裂力学实验。
摘要（英）：

The utility model discloses a monitoring system for super dynamic strain fields in rock blasting, which can obtain a dynamic fracture mechanics experiment effect under blast load on natural rocks. The monitoring system comprises a loading unit, a photographing unit, a light source unit and a synchronization unit, wherein the loading unit is used for carrying out blast loading on natural rock test blocks and generating super dynamic strain fields in the test blocks; the photographing unit is used for alternatively photographing or synchronously photographing the dynamic fracture process in the natural rock test blocks through at least two digital imaging subunits to obtain crack propagation images at different moments; the light source unit is used for providing illuminating ray or reinforcing illuminating ray for the natural rock test blocks; the synchronization unit is used for synchronously controlling the actions of the loading unit, the photographing unit and the light source unit. The monitoring system is suitable for dynamic fracture mechanics experiments under blast load on natural rocks.
