摘要
对高应力膨胀软岩条件下的巷道底鼓机理进行了分析,提出了复杂条件下复合型底鼓的力学模型,推导了巷道底板塑性区范围及底板压力的本构方程,达到了控制巷道底鼓变形的效果。
The mechanical of roadway floor heave under higstress conditions of swelling soft rock was analyzed,the dynamimodel of compound floor heave under complex condition was proposed, the scope of roadway floor plastic zone and constitutive equation of floor pressure were deduced, achieved good effect ocontrolling deformation of roadway floor heave.
