基于电缆传感器乌鲁木齐地铁沿线地温分布规律观测研究

Urumqi cable sensor MTR geothermal distribution observational studies based on

通过对乌鲁木齐地铁沿线3个典型地貌单元的地层温度长期观测研究,得到不同地貌单元地层的恒温层位置和冬季至夏季地温的分布规律。观测结果表明:剥蚀丘陵区的恒温层在地表10m以下,恒温层温度为12.5℃;乌鲁木齐河阶地区的恒温层在地表9m以下,恒温层温度为12.7℃;山前冲、洪积倾斜平原区的恒温层在地表9m以下,恒温层温度为13℃。观测研究结果可为地铁车站和区间隧道的空调系统的设计提供参考。

With a study on the long-term geothermal changes of three typical geomorphic units along Urumqi Metro lines, Get the constant temperature strata position in different geomorphic units and the distribution law of the geothermal formation form win- ter to summer. The observation results show that the constant temperature strata of Denudation hilly region is under 10 meters of the ground, and the temperature at this position is 12.5℃; while the constant temperature strata of Urumqi River terrace region is under 9 meters of the ground, and the temperature at this position is 12.7℃; the constant temperature strata of Piedmont alluvial and diluvi- al sloping plains is under 9 meters of the ground, and the temperature at this position is 13 ℃. These results could provide a reference for the design of air conditioning engineering at metro stations and in the sectional tunnels.
