摘要
论述了用突变理论方法处理地压动力活动的适用性和应用前景。文中得到的地压动力现象机理是:在达到最大承载力之后,行将冲击破坏的中心部份,以其某些部位不断损伤来吸收母体及外荷载所释放(提供)的能量。当后者在单位位移中所释放(提供)的能量大于前者所能吸收的能量时,系统就失稳冲击。结果造成一部份彻底破坏而母体得以从局部卸载的局面。
Catastrophe theory is introduced briefly in this paper.And the app-lication scope and prospect of catastrophe theory in dealing with dyna-mic phenomena of rockmass is described.The mechanism of dynamicphenomena of rockmass is obtained by using catastrophe theory.Whenthe confining pressure reaches a critical value,the rock structure to bedestroyed divides into two parts:one absorbs energy by destroying itself,the other(parent rockmass)releases energy continuously.As the result,the former is destroyed complet...
