A typical gateway is analyzed using fully-deformable discrete element method. The fractured zone around the gateway is measured in field. Based on the measurement results and theoretical analysis, a comprehensive support scheme adopting bolt and steel belt is proposed. Discrete element method is used to assess the bolting scheme, and displacement monitoring in field is also carried out. Having been put into practice, it is proved that the scheme is both suc-cessful and rational. According to theoretical analysis and monitoring in field, some important keynotes that should be noticed in gateway bolting practice are presented as well.

采用可充分变形的离散元法,对一个倾斜煤层回采巷道的稳定性进行了分析,并进行了围岩松动范围的测试。在此基础上,提出了锚杆加钢带的巷道综合支护方案。用离散元法及现场围岩位移测试对支护方案的合理性进行了评价。经施工验证,支护方案是成功可行的。根据分析和现场观测,提出了倾斜煤层回采巷道锚杆支护应注意的问题。

【期刊论文】在地震载荷作用下的节理岩体地下洞室围岩稳定性分析

节理岩体的力学性质主要由节理控制,在地震动载荷的作用下,节理可能滑移、张开。在有临空面时,节理岩体将表现出显著的几何非线性和大变形。地下洞室在原岩应力作用下可能还处于稳定状态,但在动载荷作用下就可能失稳破坏。本文采用了动力离散元法对一个大断面地下洞室在地震载荷的作用下的动力影响及围岩稳定性进行了分析,并模拟出围岩失稳和破坏的全过程,有助于对节理岩体中洞室围岩变形和破坏机制的认识。

【期刊论文】Dynamic discrete element method and its application in rock mass engineering①
陶连金, TAO Lian-jin, JIANG De-yi, ZHANG Zhuo-yuan

Based on conventional discrete element method, the idea and calculating method of dynamic discrete element (DDEM) was proposed, and a relevant program was developed. The application of the method is presented in rock me-chanics and engineering, which indicates that the method can be widely used in dynamic response and stability analysis of jointed rockmass under dynamic load.

地下水在节理岩体中流动时,会引起岩体中应力场与渗流场的相互作用。以节理开度变化为纽带,进行了岩体中渗流场与应力场的耦合分析,并用离散元法完成了计算,给出了计算实例。
