Abstract

A highway tunnel under construction in Honghe Prefecture, Yunnan Province was taken as the research object to study the geological genesis of high ground temperature. The tunnel has both high water temperature and high rock temperature, with the maximum water temperature of 63.4 ℃ and the maximum rock temperature of 88.8 ℃. The regional thermal control, water source, heat source, and heat conduction channel are analyzed from the aspects of regional geological structure, seismic characteristics, hydrochemical characteristics, and geothermal reservoir characteristics. The hot water source, evolution process, and origin of heat source are studied by means of hydrogen oxygen isotope analysis, strontium isotope analysis, trace element analysis, and radioactive element analysis. Based on the geological, hydrogeological and excavation conditions of the tunnel, the geological genesis of the high water temperature section and the high rock temperature section of the tunnel is dissected and discussed. The results show that the genetic process of high water temperature in limestone sections is different from that in granite sections. The genetic process of high water temperature in tunnel is “heat source (deep thermal anomaly)–main heat transfer channel (deep cycle)–secondary heat transfer channel–shallow water mixing and water rock interaction”, which is accompanied by cold and hot water mixing, ion exchange, etc.; while the genetic process of high rock temperature in tunnel is “heat source (deep abnormal body, radioactive element decay heat generation)–main heat transfer channel (deep cycle)–secondary heat transfer channel–hot gas being transmitted to the tunnel rock mass along the crack”, and the process is accompanied by the enrichment of S element, which is favorable to the formation of toxic and harmful air bag of H₂S or SO₂.
