摘要
TBM对地质条件适应性差,地质因素对TBM选型十分重要,分析TBM破岩机理,论述岩石属性包括单轴抗压强度和硬度及岩体属性包括结构面产状和完整程度等地质因素与TBM掘进效率的关系,给出了根据地质条件进行TBM选型的工程实例。
The geological factors are very important for selecting the type of TBM due to its poor adaptability to geological conditions. This paper analyzes the cutting rock mechanism of TBM and describes the rock properties such as single-axial compressive strength and toughness, the occurrence of structure plane and integrality, and the relationship of these geological factors with tunneling efficiency. Then it gives an project example of type selection of TBM based on geological conditions.
