多检距地震电缆是在水利水电工程地震勘探中,为适应勘测设计不同阶段探测不同结构面时所需精度而设计的,它把原检波距为等距的电缆设计成各种不同检波距的电缆,它由多节不同检波距的电缆组成。工作时,只需将电缆通过功能转换接头便可直接接入地震仪。使用这种电缆与原单检波距电缆比较,可根据不同的要求任意选择点距,使勘探经费大大地节省,工作效率可成倍地提高,特别是对资料解释工作有很大的益处,它是地震勘探中十分实用的电缆。根据湖南省水利水电勘测设计院从美国进口的Es——1225型12道地震仪把检波距设计成5米、10米、20米、30米。试制后的电缆通过湖南洮水电站试验和使用,证实了它的可靠性和实用性,完全达到了设计要求。
In the seismic exploration of water conservancy and hydropower engineering, multiseismic seismic cable is designed to meet the precision required to detect different structural planes in different stages of surveying and designing. It designs the cables whose original detection distance is equidistant to different detection distances Cable, which consists of multiple sections of different cables from the detection distance. When working, simply connect the cable to the seismometer with a functional adapter. The use of this cable compared with the original single detection cable, according to different requirements of arbitrary choice of pitch, so that substantial savings in exploration costs, work efficiency can be doubled, in particular, the data interpretation of great benefits, it is Seismic exploration is very useful cable. According to the 12 - type seismograph Es - 1225 imported from the United States according to Hunan Provincial Institute of Water Conservancy and Hydropower Survey and Design, the detection range is designed to be 5 meters, 10 meters, 20 meters and 30 meters. After the trial of the cable through the hydropower station in Hunan test and use, confirmed its reliability and practicality, fully meet the design requirements.
