摘要
长大铁路干线设计前期的地质勘察十分重要,地质勘察的手段往往是通过钻探取芯的方式来探明路基的地质情况,而钻探存在着投资大,以点带面等不足。相比较而言,高密度电法勘探具有投资小,连续性勘察等特点,但由于地下情况复杂多变,造成电阻率成果解译相对困难。将钻探控制与高密度电阻率法联合进行地质勘察的方法加快了勘察进度,更好地指导了实践。
The prior geology investigation is very important for the design of a long railway.The drilling is usually used for geology investigation to probe the railway subgrade,but the drilling has a huge amount of investment and can just investigate the region nearby borehole seprately.However,the high density resistivity method has a small amount of investment and can explore the subgrade continuedly.Because of the complexity of geological condition below surface,it is very difficult to bring an accurate explanation for high density resistivity method.So we combine the drilling method with the high density resistivity method perfectly,which makes the period of geology investigation shorter,the investment smaller and the geological explanation better.
