摘要

采用自行设计的岩石材料破坏过程变形场监测系统(Geo-DSCM系统)，观测了受单轴压缩的岩石圆孔结构破坏过程中的变形场演化。圆孔结构由大理岩方板在中心钻孔加工而成，以0.02 mm/min的位移加载速度进行单轴压缩至破坏。实验结果表明，载荷水平较低时圆孔结构的拉应力集中部位发生变形集中现象；当载荷水平接近加载曲线的峰值点时，变形集中在两条共轭的与加载方向成一定角度的局部化带上；之后，变形的集中迁移到其中一条带上集中，结构最终在此带上形成宏观裂纹而破坏。

Abstract

The failure procedure of a rock borehole structure is experimentally studied using a specially designed deformation field inspection system (Geo-DSCM system). The borehole specimen

which is manufactured by drilling a hole at the center of a marble plate

is uniaxially compressed to failure with the speed of 0.02 mm/min. Deformation fields through all the loading procedure are inspected and analyzed. It is shown that the deformation field localizes on the sections in tension at the early stage of loading.. While when specimen is loaded almost to the peak of loading curve

two new X-shaped localization bands

which are at angle from the loading direction

occurred. Finally only one localization band maintained and formed the macro fracture that failed the structure.
