摘　　要：在工程建设过程中,由于地质情况差异很大,在进行地基处理时,差异也很大。在进行基础施工时,虽然岩基场所不需要打桩,但岩基电阻率很大,给电力系统、防雷系统、电子信息设备的接地带来极大困难,所以需要从工程地质详细勘察阶段开始,对接地施工方案进行详细的策划和设计,一旦施工完成,再对达不到规范要求的接地电阻实施补救将非常困难,成本也很高,而且效果也不会很理想。为此,在岩基场所采取非常规的技术措施是非常必要的。In the process of engineering construction,due to the great difference in geological conditions,there are also great differences in the foundation treatment of the built structures.In the foundation construction,although there is no need to pile in the rock foundation site,the resistivity of the rock foundation is very large,which brings great difficulties to the grounding of the power system,lightning protection system and electronic information equipment.Therefore,it is necessary to plan and design the grounding construction scheme in detail starting from the detailed survey stage of Engineering geology.Once the construction is completed,it will be very difficult to remedy the grounding resistance that does not meet the specifications,it will be costly,and the effect will not be good.For this reason,it is very necessary to take unconventional technical measures at rock foundation sites.
