3 General Provisions
3.0.1 The geophysical exploration used in hydrogeological and geotechnical investigation for electric power construction purposes is collectively called electric power engineering geophysical exploration (hereinafter referred to as geophysical exploration). Nowadays commonly used methods include electrical method, seismic method, well logging method, rock-soil in-situ test, non destructive testing of piles, underground pipelines and cables detection technology, radon detection technology, sonic test technology, and Rayleigh wave test technology.
3.0.2 Geophysical exploration is an important means of geological exploration, ground treatment, and quality examination. Its proper use in conjunction with electric power surveying and design characteristics may help improve the surveying quality, shorten the time, and reduce the cost.
3.0.3 Geophysical exploration must be carried out in close conjunction with geological survey. Attention is drawn to tests and determination of various physical parameters of rock and soil, which shall be utilized in an extensive manner to overcome the limitations of a single method in conditional use and multiple interpretations, and obtain correct conclusions.
3.0.4 New geophysical exploration technologies shall be actively used and promoted. Attention is to be given to the verification of geophysical exploration results and the return visit for geologic effects.
3.0.5 In electric power engineering, the geophysical exploration work processes are generally as follows: acceptance of task; data collection; reconnaissance survey; plan preparation; method testing;field work; data organization; submission of results. The above processes may be streamlined under special circumstances.
