我院物探组在陕西省地质局物探队、冶金部武汉勘察公司的帮助下,曾在湖北襄樊第四纪松散层地区和武汉石炭二叠纪灰岩地区进行了衰变场法初步试验。根据试验结果,初步认为,衰变场法对于区分富水与贫水区效果较好;对于含水层位的确定,在第四纪地层中具有明显的规律性,在灰岩地层,其规律性则不强;对于涌水量的估算上,用公式算的结果与实际相比较,误差较大,一般是估算的涌水量偏大。
With the help of Geophysical Team of Geological Bureau of Shaanxi Province and Wuhan Prospecting Company of Metallurgical Department, our geophysical prospecting team conducted the initial decay field experiment in the Quaternary loose area of Xiangfan, Hubei Province and the Carboniferous Permian limestone area of Wuhan. According to the test results, it is preliminarily believed that the decay field method is better for distinguishing between water-rich and water-poor areas. For the determination of aquifer, there is a clear regularity in Quaternary strata. In limestone stratum, the regularity Not strong; for the estimation of water inflow, the results calculated using the formula compared with the actual, the larger the error is generally estimated gushing water is too large.
