The mechanical property of surrounding rocks is the important factor which must be considered in TBM cutter design. At the same time, the factor has a close relation to the overall design of TBM and the feasibility of excavating tunnels with TBM. It is not perfect to select the parameter system whose key parameter is unconfined compressive strength (UCS). In the boring process, the rocks below the cutter are exerted on by vertical compressive stress and sink, and the rocks beside the cutter are compressed in the direction of face and swells. In the deformed rocks, the tensile or tensile shear cracks appear. When the swelling areas between two cutters are superimposed, the deformed rocks are separated from the face. Under the cutter load, the larger the relative displacement between two points in the face is, the more advantageous to boring it is. The relative displacement is directly controlled by elastic modulus (E) and poisson′s ratio (μ). To sum up, in addition to UCS, E and μ should be taken into account in TBM cutter design.

围岩力学特性是隧道掘进机———TBM刀具设计中必须考虑的重要因素 ,而且这一因素也直接关系到TBM的总体设计及选用TBM施工的可行性。选择以单轴抗压强度为核心的参数系统作为刀具设计依据是不完善的。TBM掘进过程中 ,刀具正下方因承受纵向压力而下陷 ,刀具两侧附近岩石由于受到平行掌子面的挤压而隆起。岩石下陷和隆起的同时 ,其内部出现张性或张剪性破裂面。当相临刀具诱发的隆起区重叠时 ,岩石便以碎块的形式脱离掌子面。在刀具荷载作用下 ,掌子面上两点之间的相对位移越大 ,对掘进越有利 ,而不同点之间的相对位移受岩石泊松比 μ和弹性模量E的控制。较大的 μ、较小的E对TBM掘进是有利的。除了单轴抗压强度外 ,刀具设计还应综合考虑变形参数 μ和E 。

In this paper, the state of rock debris cutted off by TBM in different geological conditions is presented. The surrounding rock can be understood by means of rock debris observation, which is significant to TBM construction.

文章介绍了围岩在TBM刀具作用下,不同地质条件下形成的岩碴的状态。通过对岩碴的观测,适时反映出开挖面围岩的情况,对TBM施工具有指导意义。
