摘要
以某浅埋地下硐室两处围岩破裂区域为研究对象,采用Visual Basic语言编制了赤平投影及实体比例投影程序,方便地判断了楔形体的滑动方式,给出了有关滑动参数及其相应的稳定性系数,并方便地计算了锚杆孔合理位置及锚固段加自由段长度,给出了锚固力和稳定性系数之间的关系方程与变化曲线。赤平极射投影的程序化,对楔形体稳定性定量分析具有重要意义,对锚杆参数优化有一定的工程应用价值。
In this paper,two rock failure areas in one shallow underground chamber were taken as the study object. By using a program of stereographic projection and entity proportion projection written by utilizing Visual Basic language,it conveniently judged the sliding mode of wedge, giving out the related sliding parameters and the corresponding stability coefficient. It calculated the rational position of bolting holes and the anchorage free length, giving out the relational equation and varying curves between the anchoring forces and the stability coefficients. The programmed stereographic projection is of great significance in quantitative analysis of wedge stability, which has a certain engineering value in anchor bolt optimization.
