摘要: 抗浮设防水位的高低,直接影响建筑的造价和安全。从规范的定义出发,通过实例阐述了斜坡地段的抗浮水位宜按地下水渗流关系确定上下游的抗浮水位;场地及周边地区存在大面积回填时,应考虑施工回填导致地下水位壅高;施工期和使用期场地条件变化较大时,可分别建议不同时期的抗浮设防水位。

Abstract: The groundwater level for uplift control directly affects the construction cost and the structure safety.This paper starts from the definition of the groundwater level for uplift control in the design code. Then, the paper presents a case history of determination of groundwater level for the uplift control in accordance with groundwater seepage relations. When a large area of high fills on the site, the effect of raising the groundwater level should be considered int eh design. Different groundwater level for the uplift control during construction and the service.

Key words: Geotechnical Investigation, Groundwater, Groundwater Level for Uplift Control
