一、前言岩石基础简称岩基,是一种以天然岩体为地基和基础的基础形式,它是把锚筋或地脚螺栓直接嵌入岩体里,用固结剂与岩体造成一体。这种基础具有较高的抗拔能力,最适用于承受上拔力、倾覆力的输变电杆塔等工程。它具有成本低、施工方便、周期短等优点。以500千伏线路2B_5-33型塔型为例,如采用现浇混 I. Introduction The rock foundation, referred to as rock foundation, is a basic form based on natural rock as foundation and foundation. It anchors anchor bolts or anchor bolts directly into the rock mass, and is used to integrate the anchoring agent with the rock mass. This kind of foundation has high anti-extraction capability and is most suitable for projects such as power transmission and transformation towers that can withstand upward pull-out forces and overturning forces. It has the advantages of low cost, convenient construction and short cycle. Take a 500 kV line 2B_5-33 type tower as an example.
