2010年唐山矿井水位上升速率明显加快,上升幅度明显高于往年同期。本文从地下水动力学和荷载效应角度,利用抽（注）水试验模型和均布荷载下半无限大的弹性空间理论模型,分析井孔附近楼盘施工注浆及建成后荷载作用对井水位的影响。结果表明,距井孔200～700m范围内注浆,每天注浆2500m3,注浆270d,能引起井水位上升8～11m的变化;大面积的楼盘荷载作用可以引起井水位上升约4m的变化。通过对这些影响因素的分析,认为唐山矿井水位的上升异常与楼盘施工注浆及建成后的荷载作用有一定的相关性。

The water level rising rate of Tangshan mine well significantly accelerated in 2010, and the ascensional range was obviously higher than the same period in previous years. From the point of view of groundwater dynamics and loading effects, using the pumping （pouring） water test model and semi-infinite elastic space theory model under uniform load, grouting and loading of the near building construction were analyzed. Results represent that range of 200 - 700m grouting, daily grouting 2500m3 , grouting 270d, can cause rising change in 8 - 11 m of well water level, and loading of large area of the near building can cause about 4m changes of well water level. The analysis of these factors shows that water level anomalous rising of Tangshan mine well was relevant to grouting and loading of the near building construction. This study provides a scientific basis for anomalous rising analysis of water level in Tangshan mine wells.
