水对大理岩岩爆影响的模拟实验研究

Simulation Experimental Study on the Effect of Water on the Marbme Rockburst

通过双向加载模拟了大理岩含水与干燥情况下的岩爆,记录了声发射特性。分析了含水和干燥情况下岩爆现象、声发射特性及其原因。提出水对防治岩爆的积极作用和声发射预测岩爆的可行性。

The paper describes the acoustic emission character based on two of the saturation marble and dry marble axial compression test to simulate rockburst. Through the difference condition of saturation marble and dry marble test result,the rockburst phenomenon,acoustic emission character and the reason are analized. At last, the thesis shows that the ability of wafter can prevent rockburst and acoustic emission character can forecast rockburst.
