一、岩体结构的数值模型作为工程对象的岩体是十分复杂的。历经地质年代里无数次地质构造运动,岩体中生成了错综复杂的结构面。这些结构面将岩体切割成块体结构。为了能够在岩石力学中运用数学分析的方法,就需要把实际的、貌似杂乱无章的岩体,抽象为某种数学力学模型。 First, the numerical model of the rock mass structure The rock mass that is the engineering object is very complicated. After numerous geologic tectonic movements in geological times, intricate structural planes were created in the rock mass. These structural planes cut the rock mass into a block structure. In order to be able to use mathematical analysis methods in rock mechanics, it is necessary to abstract the actual, seemingly disorderly, rock masses into a mathematical mechanics model.
