地下工程对地下流场变化影响——以黔中白云岩区为例

Influence of underground engineering on changes of underground flow field——Taking the dolomite area in central Guizhou

以贵安新区贵安高铁站区域地下水动态监测数据为依据,分析研究地下水流场受地下工程的影响和演化过程。结果表明:研究区在白云岩含水岩组中地下水受地下工程阻滞,其水位动态特征与自然条件相比变化较大;地下水位显著上升,其浮托力增大,将导致原有抗浮工程失效。了解工程建设对地下水流场的影响及其产生机理,有助于推动地下工程技术的发展。

Based on the groundwater dynamic monitoring data of the Gui’an High-speed Railway Station in the Guian New Area,the influence and evolution process of the groundwater flow field by underground engineering is analyzed and studied.The results show that the groundwater in the dolomite water-bearing rock group in the study area is blocked by underground engineering,and its water level dynamic characteristics have changed greatly compared with natural conditions;the groundwater level rises significantly,and its floating power increases,which will lead to the original anti-floatation The project failed.Understanding the impact of engineering construction on the groundwater flow field and its generation mechanism will help promote the development of underground engineering technology.
