摘要
为减小轨道交通工程建设对地下温泉资源的影响,以市郊铁路重庆中心城区至南川线工程对重庆市东温泉地热资源的影响为研究背景,结合温泉热储构造对线路避让东温泉地热资源的线、站位方案进行了深入分析.结果表明:线路采用路基和高架敷设不影响东温泉地热水资源的补给、径流与排泄;线路采用隧道敷设时不得穿越热储层,可穿越热储盖层,但须完全位于热储盖层范围内,才不会引起东温泉地热水的衰减和流失.研究结果为今后轨道交通穿越温泉地热资源提供了参考和借鉴.
Abstract
In order to reduce the impact of rail transit engineering construction on underground hot spring resources,taking the impact of the suburban railway of Chongqing Central City-Nanchuan Line Project on the geothermal resources of the East Hot Spring in Chongqing as the research background,and combine with the hot spring reservoir structure,the scheme to avoid the line and position of geothermal resources of the East Hot Spring is further analyzed.The result shows that the subgrade and overhead laying of the line can not affect the supply,runoff and discharge of the geothermal resources of the East Hot Spring.When the line is laid in a tunnel,it is not allowed to pass through the thermal reservoir layer,and can pass through the thermal reservoir cover layer,but it must be completely within the range of the thermal reservoir cover layer,which can avoid the attenuation and loss of geothermal water in East Hot Spring.The research results provide the reference and inspiration for the rail transit crossing the hot spring geothermal resources in the future.
