地下车库的抗浮验算

Checking Calculation of Water Float Acting on Underground Garages

指出在验算地下车库抗浮问题时,不根据土体的特性,统一按其排开水的体积计算水浮力的不合理性,并从理论上较深入地分析了原因,同时提出了一个较合理的解决方法,即根据地下车库所处不同的土层情况来确定其相应浮力的计算方法,并给出一个具体的工程实例,说明了其在工程上的应用价值。另外,提出工程界有必要进一步深入研究,以设计规范或规程的形式明确折减系数ψ值的试验方法和合理取值,以使地下车库水浮力的设计取值能够规范化和统一化。

The limitation of the calculation of water float acting on underground garages according to the water volummn is summarized up in the paper.The reason is theoretically given.At the same time,in order to discuss the calculation of water float acting on underground garages,an appropriate solution is given.In the end of the paper an example is presented to show the importance in the engineering.In addition,the suggestion that a thorough search about the coefficient ψ should be carried out in the engineering is present in the paper,in order to standardize of the calculational methods abuout the water float acting on underground garages.
