| Abstract: | The temperature and its gradient is measured carefully in 6 wells of Jinshajiang groundwater observation network.The result shows that the influence depth of sun-radiation heat is 50～125m.The average water temperature gradient is different in deferent wells,the minimum value is 0.11℃/hm,the maximum is 2.81℃/hm,and the general is 1～2℃/hm.The temperature gradient diversity in deferent depth sections in one well is very obvious,with values being in decimal fraction of ℃/hm,and the larger ones being 4～5℃/hm.Lithology of stratum and completeness of rockmass,particularly the high-angle fault crush zone,play a major role in affecting the influence depth of sun-radiation heat and temperature gradient of each well.The micro-behavior characteristics of water temperature in well,e.g.co-seismic effect,tide effect and anomalies before an earthquake etc,depend largely on the temperature gradient of the depth section where the temperature sensor is fixed. |
