地下水对建筑工程设计施工中的影响

地下水的浮力对结构设计和施工有不容忽视的影响。结构抗浮验算与地下水的性状、水压力和浮力、地下水位变化的影响因素及意外补水有关；提出了设计水位计算浮力的概念。对结构设计中需处理好的地基反力与地下水浮力和水压力、结构整体抗浮与局部抗浮、结构布置和构件验算等一系列问题进行了讨论，提出了抗浮设计的方案及措施。

Some Influence of Groundwater on Design and Construction of Building Structure

s: The ground water would influence the design and construction of building structure because of buoyancy. The computation that is to check the anti-overturning of structure is related with property, water pressure, buoyancy, influencing factors of groundwater variation and water replenishing. What's more, the concept of design water level is put forward. Through the analysis of practical engineering and criterions, a series of problems are discussed which include the relations between ground counterforce and buoyancy and pressure of groundwater, integral anti-overturning and local anti-overturning of structure, array of structure and checking computations of construction members. In the end, project and measures of anti-overturning design are put forward.
