Embodiment Construction

[0030] The present invention will be further described below with reference to the drawings and embodiments, and the content of the embodiments is not to limit the protection scope of the present invention.

[0031] figure 1 It shows a flow chart of the method for forecasting the location of tunnel gushing water in advance according to the present invention. Such as figure 1 As shown, the method for predicting the location of tunnel water gushing in advance of the present invention includes the following steps:

[0032] First, the single-well isotope tracer method is used to measure the hydrogeological parameters of the groundwater seepage field. In the present invention, such as figure 2 As shown, the use of single-well isotope tracer method to measure the hydrogeological parameters of the groundwater seepage field is specifically as follows: select a location above the tunnel for drilling, and then put the radioisotope tracer into the well, and then use the radioactive detector ...

Abstract

The invention relates to a method for advanced forecast of a tunnel water inflow position. The method comprises the following steps: firstly measuring the flow rate and the flow direction of underground water at any space point in an underground water seepage field by utilizing a single well isotope tracer method, then establishing a concept model, deducing the rough water inflow position and the water inflow through mathematics deduction, finally performing local temperature measurement and drilling and obtaining the accurate water inflow position according to the temperature effect of the underground water on a rock body. The method provided by the invention has the benefits that the accuracy is high, the workload is reduced, and the effect of human factors is avoided; meanwhile, the method is not affected by tunnel construction and also has no effect on the tunnel construction, and the tunnel forecast efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of tunnel construction, relates to a tunnel construction geological advance prediction technology, and specifically relates to a method for advance prediction of the location of the tunnel water gushing. Background technique [0002] Among the various geological advanced forecasting methods at present, there is still a lack of effective means for water forecasting. The main technical methods used in the prediction of the tunnel water gushing location include: interface location combined with geological analysis method, infrared detector water detection method, geological radar water detection method, rock temperature gradient method and borehole water detection method. [0003] Among them, the interface position combined with the geological analysis method uses various geological prediction methods other than the drilling method, the advanced pilot pit method, and the parallel advanced pilot pit method to determine...
