Embodiment Construction
[0029] Such as figure 1 Shown: a construction geological prediction system for tunnels passing through coal-measure strata, the following steps are adopted:
[0030] Step 1, macro analysis: consult a large number of survey data and design drawings, and have a comprehensive understanding of the geological conditions of the project area. Through the analysis of the previous data, combined with the forecast of the excavated section and the actual excavation, the overall Grasp the distribution of coal measure strata;
[0031] Step 2, on the basis of macroscopic analysis, according to the specific situation, carry out specific analysis on the situation of the tunnel passing through the coal-measure strata by means of geological records, geophysical prospecting analysis or advanced drilling;
[0032] The geological record is to reflect the exposed stratum, lithology, geological structure, groundwater and other unfavorable geological phenomena on the display of the cave body or the ...
