摘要
采用岩块及结构面力学参数对节理岩体的稳定性进行计算与分析,是一个值得探讨的课题。本文根据节理结构特征及节理岩体变形的时效特性,建立了断续节理和连续节理岩体的弹性粘塑性两种数学模型,并提出了节理岩体边坡安全度的计算方法。通过实验模型验算及边坡工程实例计算与分析,证明本文的数学模型与理论分析是正确而可靠的。
The calculation and analysis of jointed strata stability surface is a question worth study and discussion. On tha basis of jointed structure feature and time effectiveness feature of jointed strata deformation,two elastic-vis-co-plastic mathematical models for discontinuous and continuous jointed rock strata are established and a calculrtion method of slope safety level in jointed rock mass is proposed, laboratory model checking computation as well as field case calculation and analysis proved the mathematical models and theoretical analysis to be rational and reliable.
