| 摘 要： | 恒温层深度的预测与地热能开发利用、地下空间建设等密切相关,陕西省区域恒温层的研究工作进展较慢。通过探讨恒温层深度的影响因素认为: 导热系数与恒温层深度呈弱负相关; 地表与大气间表面传热系数与恒温层深度呈弱正相关; 大气温度年振幅与恒温层深度呈正相关; 导温系数与恒温层深度呈明显的正相关。介绍并验证了一种土壤恒温层深度的计算方法,通过该方法,计算了全省不同地貌单元恒温层深度的理论值。全省恒温层深度介于10.5~23.8 m之间: 陕北地区恒温层深度为10.5~23.8 m; 关中盆地恒温层深度为11~17.4 m; 陕南地区恒温层深度为11.7~18.6 m。该研究系统地划分了陕西省区域恒温层的深度范围,为陕西省“绿色”追赶超越政策的实施做出贡献。

| Abstract: | The prediction of the constant-temperature layer depth is closely related to geothermal energy development and underground space construction. Progress of research on regional constant-temperature layer in Shaanxi Province is relatively slow. This paper discusses the influencing factors of the constant-temperature layer depth and the results show that there is an inverse correlation between the thermal conductivity and the constant-temperature layer depth. And the surface heat transfer coefficient between the surface and the atmosphere is positively correlated with the constant-temperature layer depth. Besides, the annual amplitude of the atmospheric temperature is positively correlated with the constant-temperature layer depth. The thermal conductivity coefficient and the constant-temperature layer depth showed a significant positive correlation. This paper describes and validates a method for calculating the constant-temperature layer depth. And the authors calculated the theoretical value of constant-temperature layer depth for different geomorphic units by using this method. The constant-temperature layer depth is between 10.5 m and 23.8 m for the whole province and is between 10.5 m and 23.8 m in northern Shaanxi Province, with 11~17.4 m in Guanzhong Basin and 11.7~18.6 m in southern Shaanxi Province. The depth range of the regional constant-temperature layer in Shaanxi Province has been systematically divided in this research and this paper has contributed to the implementation of Shaanxi’s “Green” Catch-up and Transcendent policies. |
