In order to study the safety of each part of the rock mass, the element safety factor Ke is proposed to estimate the micro-stability of the rock mass. The element safety factor can reflect the stability state of the rock mass under the earth stress. A formula for the element safety factor is derived by a theoretical analysis, and the influential factors for the element safety factor are studied in selected cases, which show that, (1) with the increase of shear strength, cohesion c and friction angle ?准, the element safety factor Ke increases in a linear relation between Ke and the shear strength, and with the increase rate of Ke with respect to cohesion c greater than that with respect to friction angle, so the cohesion has a larger effect on the element safety factor than that of friction angle; (2) the increase of the minimum principal stress will lead to the increase of the element safety factor, while the increase of the maximum principal stress will lead to the decrease of the element safety factor, which is in accordance with the real situation, and they are both in an exponential relation., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null,

articleAbstract=岩体稳定性评价是岩体工程设计和施工的重要内容，为了探讨岩体各部位的安全情况，引入单元安全系数Ke来评价岩体的微观稳定性，它能定量评价岩体在应力作用下的稳定状况；通过理论分析，推导了单元安全系数公式，然后，利用算例研究，探讨了单元安全系数的影响因素。研究表明：① 随抗剪强度参数、黏结力c、内摩擦角?准的增大，单元安全系数Ke逐渐增大；Ke与抗剪强度参数间符合显著线性关系；Ke随c变化的梯度明显大于Ke随?准变化的梯度，黏结力对单元安全系数的影响大于内摩擦角对单元安全系数的影响；② 最小主应力增大引起单元安全系数增大，最大主应力增大引起单元安全系数减小，符合实际情况，并且二者与单元安全系数的关系均呈现指数关系特征。,
