Research on High Geothermal in Complex Deep Buried Tunnel Environment

An effective and practical three-dimensional modeling method and analytical theory of high geothermal in complex deep buried tunnel environment based on voxel model and Kriging algorithm was proposed after considering the effects of spatial correlation, adaptation and accuracy of relevant parameters, which can accurately prevent and control the high geothermal disaster risk in complex deep buried tunnel environment. Compared with the results of classical tunnel models, it is found that the proposed three-dimensional modeling method and analytical theory of high geothermal in complex deep buried tunnel environment was effective. Secondly, the three-dimensional modeling method and analytical theory had a good application prospect in the field of high geothermal heat damage area, and can effectively reveal the spatial distribution characteristics of high geothermal heat damage area. Finally, the proposed method can provide theoretical foundation and thought innovation for precise prevention and control of high geothermal disaster risk in complex deep buried tunnel environment, and has good practical significance and scientific value.
