摘要：
In order to reveal the mechanism of rock breaking of abrasive water jet, experiments of abrasive water jet erosion on typical brittle rock(siliceous limestone) were carried out and CT scanner was used. The image processing technique and binarization processing of CT image were used to directly capture the rock fracture and damage under the abrasive water jet. The results showed that in the process of rock erosion, in addition to the rock removal and an erosion hole in the interior of the rock formed by circular cross-sections and "V" shape vertical structure. A large number of small cracks appeared on the hole wall, which damaged rock within a range. The results verified the existence of damage properties under abrasive water jet erosion. © 2016, Science Press. All right reserved.
