Abstract为了研究影响全断面岩石掘进机(TBM)掘进速率的地质因素,利用三维离散元程序3DEC建立TBM滚刀破岩三维仿真模型,分析不同的地质条件对TBM掘进速率的影响,根据TBM在围岩中的可钻性对南水北调西线工程中的围岩进行分类.分析结果表明:TBM掘进速率与岩石物理力学性质及岩体中的节理条件密切相关,在一定范围内,围岩强度越低,节理分布越密集,TBM掘进速率越高;而围岩强度越高,节理间距越大,使得TBM掘进速率大大降低
Other AbstractIn order to study the geological factors which impact penetrating rate of tunnel boring machine(TBM), this paper uses three-dimensional discrete element model 3DEC to build simulated models on rock fragment by TBM cutter. It analyzes the influence of different geological conditions on TBM penetrating rate and classified the surrounding rock in west route of south-to-north transfer project according to the drill ability of TBM in surrounding rock. The results show that the penetrating rate of TBM is closely related to the mechanical properties of rock and joint conditions in rock mass. In certain extent,TBM penetrating rate will be increased with the decrease of rock strength or closely distributed joints. TBM penetrating rate will be decreased with the increase of rock strength or rarely distributed joint. Another result is that the surrounding rock by TBM penetrating can be divided into three classes based on the drill ability of TBM in surrounding rock, which can guide the TBM penetrating
