城市小区地下水流场分析与水位控制设计

Analysis on Groundwater Flow Field and Design of Water Level Control of Urban Communities

随着城市建设用地日趋紧张,加上城市绿化、美化、园林化、海绵化等要求的提高,建筑物遭遇高地下水位地层的可能性也大大提高,增加了地下建筑物防排水设计的难度。通过对已有建筑物地下室渗水问题的处理,从勘察、分析、计算和设计的方法等角度进行了阐述,认为根据事前充分进行的工程地质和水文地质勘察,认真分析研究地下水补排条件,结合精心的设计与施工,完全可以将高地下水位带来的不利影响控制在预期的目标范围之内,可为同类项目的设计与施工提供借鉴。

With the getting scarce land for city construction plus the requirements for enhancing the urban landscaping,beautifying,afforestation and sponge,the possibilities of the buildings encountering the high underground water level stratum are also much higher,which will increase the difficulties of the waterproof and drainage design of the underground buildings.Through the treatment of the basement water seepage of the existing buildings,the methods of survey,analysis,calculation and design are expounded.It is considered that the adverse effect brought about by the high groundwater level can be completely controlled within the intended target range according to the engineering geology and hydrogeological investigation fully carried out beforehand,earnest analysis and study on the conditions of groundwater recharge and drainage,and combined with elaborate design and construction,which can be referred for the design and construction of the similar projects.
