基于数值试验的地矿类专业岩石力学实验教学改革

摘要

给出了基于数值试验的地矿类专业岩石力学实验教学改革的整体思路,并结合非标准事件压缩破坏、煤矿开采诱发岩层移动、锚杆锚索支护巷道围岩变形与破坏演化过程等试验做了初步的实践尝试与分析.实践表明,数值试验可对由于时间、经费、难度等条件制约而无法实验再现的现象进行模拟再现,并可补充常规的实验教学,把破坏过程中的应力场、位移场直观、生动、实时地展现出来.%The overall idea of the experimental teaching reform of rock mechanics for the geology and mineral majors based on the numerical test is presented,and in combination with the test of the non-standard event compression failure, coal mining induced strata movement, deformation and failure evolution process of roadway surrounding rock supported by the bolt and anchor rope,etc.,the preliminary practice and analysis are carried out.The practice shows that numerical test can simulate and reproduce the phenomena that cannot be reproduced due to conditions such as time,money,difficulty,etc.The numerical test can supplement the conventional experimental teaching and show the stress field and displacement field directly,vividly and real time in the process of failure.
