摘　　要：通过对西安地铁沿线的皂河一级阶地、黄土梁洼地、渭河一级阶地和渭河三级阶地等4个典型地貌单元的土壤进行地温观测研究,得到冬季不同地貌单元地层的恒温层位置和冬季地层地温的分布规律。观测结果表明:皂河一级阶地的恒温层在地表以下6m,恒温层温度为16℃;黄土梁洼地恒温层在地表以下7.5m,恒温层温度为17℃;渭河一级阶地恒温层在地表以下7.5m,恒温层温度为16℃;渭河三级阶地恒温层在地表以下7.5m,恒温层温度为16.5℃。研究结果可为地铁车站和区间隧道的空调工程设计提供参考。With a study on the long-term geothermal change of four typical geomorphic units along Xi＇ an Metro lines the constant temperature strata position of different geomor phic units formed during winter times is obtained, the distri bution law of the geothermal formation in winter is discov ered. The observation results show that the first terrace o the constant temperature strata position by Zao River is meters under the surface, and the temperature at this posi tion is 16 ~C ; while the constant temperature strata positio~ of loess ridge and depression is 7.5 meters under the surface the temperature is 17 ~C ; the first terrace of the constar temperature strata position by Weihe River is 7.5 meters un der the surface, and the temperature is 16 ~C ; while th~ third terrace of the constant temperature strata position b~ / Weihe River is 7.5 meters under the surface, the temperat / ture is 16.5 ~C. These results could provide a reference fo~ / the preliminary design of air conditioning engineering at met~ / ro stations and in the sectional tunnels. /
