| Abstract: | This paper will show the importance of hydrogeologic survey in tunnel by presenting examples of troubles in tunnels' construction and administration caused by unascertained hydrogeologic conditions. A new approach named as Quantitative Remote Sensing Interpretation Application Model was put forward and the differences of this model from the traditional Qualitative Remote Sensing Interpretation Application Model in evaluating the degrees of water enrichment in tunnels were described in this paper. The core of applying this model to evaluate the water enrichment in tunnels is to assess the enrichment degrees using the empirical formula for remote sensing evaluating water enrichment degree in tunnel with quantitative remote sensing interpretation. This method is based on the remote sensing geological interpretation. It quantifies the interpretations and the factors affecting the water enrichment in tunnels, brings them into empirical formula in form of fractions, and obtains the enrichment degrees according to the derived fractions from the formula. As a focal point, this paper introduced the detail approach and steps in applying the empirical formula for remote sensing evaluating water enrichment degree in tunnel, illustrated by the two examples from qinling tunnel of Xi'an-Ankang railway and Jiazhujing tunnel of Nanning-Kunming railway.The construction has proofed these assessments and demonstrated that the predicted enrichment degrees were little different from the real ones. The paper also presented some noticeable problems encountered in application of the empirical formula for remote sensing evaluating water enrichment degree in tunnel. In the conclusion, the paper pointed out that the empirical formula for remote sensing evaluating water enrichment degree in tunnel was a new application model which was different largely from the traditional qualitative remote sensing interpretation application ones. This model made the water enrichment evaluation more reliable and its processing was more simple and feasible. No similar report on this kind of method has been found in recent data retrievals. This achievement can be applied in the hydrogeologic evaluation and predictions before tunnel constructions for railways, highways, and water conservancy works. It has beneficial effects on lowering the surveying cost, heightening the surveying quality, raising the surveying efficiency and improving labor conditions. |
