[提要]  地下水的浮力對(duì)結(jié)構(gòu)設(shè)計(jì)和施工有不容忽視的影響。結(jié)構(gòu)抗浮驗(yàn)算與地下水的性狀、水壓力和浮力、地下水位變化的影響因素、意外補(bǔ)水有關(guān)。對(duì)結(jié)構(gòu)設(shè)計(jì)中需處理好的地基反力與地下水浮力和水壓力、結(jié)構(gòu)整體抗浮與局部抗浮、結(jié)構(gòu)布置和構(gòu)件驗(yàn)算等一系列問(wèn)題進(jìn)行了討論。

The ground water plays important role in the design and construction of building structures. The resistance to float relates to the attributes and conditions of the ground water, the pressure and floatage of water, the change of water level and the sudden supplement of water. Some problems that must be dealed with in design,such as the whole and local resistance to float, the construction arrangement and the calculation of members,are discussed.
Keywords: water pressure; floatage; design water level; building structure; foundation
