According to the characteristics of sediment rock and the movement of hard and massive overlying strata,using the mechanical rules of movement based on the mechanical model of fixed beam with gravity taken into account,the judgment curves of movement modes of overlying strata were worked out and their applications were explained.
根据厚层坚硬岩层的赋存和运动特点,利用基于弹性理论、考虑岩梁体积力的厚层坚硬岩层运动规律的力学判据,给出厚层坚硬岩层运动方式的判断曲线,通过分析厚层坚硬岩层运动方式的影响因素,得出厚层坚硬岩层分层运动的可能性大、层间效应明显、关键层的“关键性”下降的结论;通过与传统研究方法的对比和工程实例分析,表明文中厚层坚硬岩层运动规律的力学判据和判断方法可对“关键层”在运动过程中的破断方式进行较准确的预测。
Meanwhile,the stress and strain of the degummed fibers were also tested,and rupture curve was shown.
