【摘要】 研究已表明岩土体中都存在结构面 ,工程岩土体的变形破坏一般受结构面控制。本文依据结构面 (断层 )优势指标综合值 (Ri)的量化比较 ,可得出各结构面 (断层 )对隧道稳定影响程度的大小 ,从而针对各结构面 (断层 )采取不同的工程措施。本文分析还表明 ,结构面和地下工程中的水害、瓦斯突出、岩体质量好坏等也有密切关系。更多还原

【Abstract】 Previous study shows that there exit structural planes in rockmass and soilmass and deformation and failure of rockmass and soilmass around engineering projects are controlled by the structural planes. Based on quantitative comparison of integrated preferred index value(R i)  of structural planes(faults), we find out the influence degree of structural planes(faults) on tunnel stability.Thus, different measures can be taken for treating the different structural planes(faults). The study result reveals that water hazard, gas outburst and rockmass quality are closely related with the structural planes.更多还原
