综合物探方法在花果山隧道施工中的应用

Application of Geophysical Methods in an Investigation of the Huaguoshan Tunnel Test Site

在花果山隧道施工过程中,应用了直流电测深法、地震折射波法、电磁频率测深,磁法、电测井等综合物探方法,为合理布置钻孔、隧道设计与施工提供了可靠资料,取得了较好的效果.

In order to speed up the coal transport from Shansi Province for export, a double track railway (the Da-Qin Line) has been constructed during the seventh Five-Year Plan period. It was designed that the railway should get past a hill with complex geological conditions. So a tunnel was required. and some engineering geological problems were wanted to be solved. By using comprehensive geophysical surveys, the geological structure and hydrogeological conditions of the construction area were proved through investigation. Valuable information were provided for the selection of the tunnel site.
