摘要
为降低高地应力对工程建设和运营的不良影响,根据工程实践以及相关学者的研究经验,通过理论推导得出了卸压爆破本构方程。将卸压爆破本构方程编成计算机语言在Matlab计算软件计算,分析计算结果得出:卸压爆破的卸压区域不超过震动区半径(2.73 m),在2倍裂隙区半径(1.60 m)处卸压效果发生突变。
In order to reduce the adverse effects of high geostress on the construction and operation of the engineering, based on the practice of engineering and the research experience of relevant scholars, the constitutive equation of pressure relief blasting is obtained through theoretical deduction. The pressure relief blasting constitutive equation is compiled into computer language and calculated by Matlab software. The results of the analysis are as follows： the pressure relief area of pressure relief blasting is not more than the radius of vibration area（2.73 m）, and the effect of pressure relief at a radius of two times of crack zone（1.60 m） is mutated.
