摘要
软弱结构面多是指在上下两层坚硬岩层间填充一定厚度的软弱岩层或破碎性物质的结构面,一般这种形式的结构面若在工程建设期间出现,具有规模较大、延展性好、破碎带宽的特点,并且软弱结构面的存在可能会造成岩层结构体出现滑动,影响岩层整体稳定性。因此,必须充分了解软弱结构面的工程地质分类,以便为工程项目建设的勘察、设计提供相应指导。论文对软弱结构面的工程地质分类进行简单分析,仅供参考。
The weak structural planes usually refer to the structural planes filled with a certain thickness of soft rock or fractured material between the upper and lower layers of hard rock. Generally, if the structural planes of this type appear during the construction period, they have the characteristics of large scale, good ductility and fractured bandwidth, but the existence of the weak structural plane may cause the sliding of the rock structure and affect the overall stability of the rock. Therefore, it is necessary to fully understand the engineering geological classification of weak structural planes in order to provide corresponding guidance for the investigation and design of engineering projects. This paper makes a simple analysis of the engineering geological classification of weak structural planes for reference only.
