建筑工程设计施工中地下水的若干影响

Some Influence of Underground Water on Design and Construction of Building Structure

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、意外补水有关,并提出了设计水位计算浮力的概念。通过对实际工程的分析总结及对规范的理解,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,最后提出了抗浮设计的方案及措施。

The underground water would influences the design and construction of building structure because of buoyancy. The computation of the anti -overturning of structure is related with property, water pressure, buoyancy, influencing factors of underground water variation and water replenishing. What＇s more, the concept of design water level is put forward. Through the analysis of practical engineering and the understanding of the regulation, a series of problems, include the relations between ground counterforce and buoyancy and pressure of underground water, integral antioverturning and local anti - overturning of structure, array of structure and checking computations of construction members, are discussed. In the end, the scheme and the measures of anti - overturning design are worked out.
