| 中文摘要: |
| 针对近代岩溶山区城镇建设中频发的地下室底板突水问题，以发生了突水的贵州省安顺市西秀区城区某建筑物地下室为研究对象，采用对场区相关资料的分析、水动力计算，以及实地钻孔水位验证等手段进行综合研究。结果表明，地下室建设导致建设场区地下水动力条件改变增加“附加水头”，是造成建筑深基坑底板突水的主要原因。在此基础上，指出了传统岩土勘察对地下室底板抗浮水位确定存在的问题，提出了工程建设“附加水头”的概念，以及“抗浮水位”和“附加水头”预测计算方法。 |

| As the basement water-inrush problem which happen frequently in modern urban and rural construction，in Anshun city of Guizhou province，a basement in Xixiu district in where water-inrush happened was taken as a example，by relevant information analysis，hydrodynamic calculation，field drilling water level verification and other methods，basement construction caused groundwater hydrodynamic condition changed and additional water head added，it’s the major reason caused deep excavation water-inrush of building.On the basis，it’s point out the traditional geotechnical investigation has certain problems in basement anti-floating water level，the concept of ‘additional water head’ in engineering construction and predicted calculation method of ‘anti-floating water level’ and ‘additional water head’ were taken out. |
