摘要文章通过对西安地铁沿线4个典型地貌单元的土壤进行长期地温观测研究，得到了秋季不同地貌单元地层的恒温层位置和秋季地层地温的分布规律，目的是为西安地铁车站和区间隧道的空调工程的设计提供参考。结果表明：皂河一级阶地地表以下12 m为恒温层，温度为15.4℃；黄土梁洼地表以下13.5 m为恒温层，温度为16.2~17.8℃；渭河一级阶地地表以下10.5 m为恒温层，温度为15.5℃；渭河三级阶地地表以下10.5 m为恒温层，温度为16.5℃。研究得到的各阶地地层的恒温层位置和温度是西安地铁区间隧道通风空调系统设计的重要依据。

Abstract： Through long-term ground temperature observation and analysis of four typical geomorphic units, the locations of constant temperature strata in different geomorphic units as well as ground temperature distribution patterns in autumn were obtained, providing an important reference for air conditioning engineering in stations and running tunnels along the Xi'an metro. The results show that the constant temperature stratum at Zaohe terrace 1 is 12m below the surface at a temperature of 15.4℃; the constant temperature stratum at the Loess ridge and depression is 13.5m below the surface at a temperature of 16.2~17.8℃; the constant temperature stratum at Weihe terrace 1 is 10.5m below the surface at a temperature of 15.5℃; and the constant temperature stratum at Weihe terrace 3 is 10.5m below the surface at a temperature of 16.5℃.
