岩体工程相似材料模拟岩体工程相似材料模拟simulating material modeling of rock engineering  yont一gongehengx一ongs一Ca一l一00 11℃n.岩体工程相似材料模拟(simulating ma‘erialmodeling of rock engineering)岩石力学模拟方法之一岩体工程相似材料模拟实验的理论基础是相似原理:若两个系统相似,则表征该两系统的对应物理量成一定比例关系,表述各对应物理量之关系的数学表达式也相同。在工程岩石力学模拟研究中,相似条件应包括几何、运动和动力相似,为保证模型相似于原型,各项相似比例系数要成一定函数关系。模型可按两种方法分类:按模型的空间形态和受力状态分类;按相似条件和实验目的分类。按模型的空间形态和受力状态分类分为二类:(l)立体模型这是按材料与组构相似的要求,对研究对象的整体所建造的实验模型,其三维空间的儿何尺寸相差不大于3一5倍,并且承受三维应力作用,使其连续于无限岩体的各边界面的法向应变为零。模型实验时,要求其中的应力状态及所进行的工程活动都相似于原型。(2)平面应变模型这是取原型的一个剖面所建造的平面实验模型。它具有一定厚度,其长宽的几何尺寸大于厚度的3~5倍,模型承受三维应力作用,保证它连接于无限岩体之各边界面上的法向应变为零。模型实验时,要求其中的应力状态及所进行的工程活动都相似于原型,但工程进度不必严格相似于原型。(3)平面应力模型除受力状态外,基本类似于平面应变模型:它只承受二维应力作用,两个主要平面是敞露的,正应力为零。因模型建造与实验都很简便,可定性研究工程岩体力学问题,使用较多。 按相似条件和实验目的分类分为两类:(”地质力学模型要求全面满足地质力学因素的相似条件,主要用于研究作为一部分地质体的工程岩体,在工程活动干扰下所具备的稳定性或崩落性。对于地质构造的模型,根据岩体具体情况和实验目的,可以只模拟主要结构面,略去次要结构面,此即所谓大块体地质力学模型(图中a);若岩体断裂构造发育,断层和节理等结构面都要模拟,模型往往组构于数万个小实体,如图中b所示,此即所谓小块体地质力学模型。(2)单因素相似模型为了研究某一因素对岩体稳定性的影响而建造单因素相似模型进行实验。如弹性相似模型,用于研究弹性范围内上程岩体的应力应变状态;节理相似模型,用于研究节理岩体的破坏机制等。 经二{纂黝 ab 大小块体地质力学模型 “大块体地质力学模型;方小块体地质力学模型 (田允明)
