摘　　要：滑移线是地基介质破裂的迹线。而滑移线网的绘制 ,不仅可加深对地基破坏机理的了解 ,而且是对极限承载力求解原理、方法和步骤的补充。本文在阐述滑移线几何性质的基础上 ,借鉴土基滑移线网的绘制方法 ,并结合Hoek -Brown准则的滑移线理论和岩基极限承载力求解方法 ,系统阐述了水平均质岩基各坡坏区的几何、力学性质。最后 ,结合算例阐明绘制滑移线网的具体步骤。Plotting characteristic net can make us better understand the failure mechanics of isotropic rock foundation and the method determining ultimate bearing capacity with characteristic theory.Therefore,on the basis of introducing the geometric and mechanics characters of characteristic line,the authors set forth the method plotting characteristic net based on characteristic theory expressed with Hoek-Brown strength with an example.It is shown that,the failure of isotropic rock foundation is identical with soil,and the plotting method is feasible to plot characteristic net for isotropic rock foundation.
