某消防泵房地下结构抗浮设计方法探讨

Research on anti-floating design method of a basement structure for fire-pump room

抗浮设计是地下水池结构及地下室结构设计中一项重点内容,需考虑整体抗浮和局部抗浮设计。介绍了工程中常用的配重法、抗浮锚杆法、抗拔桩法、盲沟排水法等抗浮方案的特点及适用性,比较了各种设计方法的经济性和选择原则,最后结合消防泵房工程实例探讨了抗浮设计方案选择原则、整体抗浮和局部抗浮设计方法,介绍了桩筏基础下的抗浮计算过程。

Anti-floating design is a major content in underground reservoir structure and basement structure.The designation should take both whole anti-float and partial anti-float into consideration.Different methods were introduced such as additional weight method,anti-floating anchor method,uplift pile method and blende drainage method.The characteristic and applicability of these methods were analyzed,also the economic and selection principle comparison is made.The project case was discussed to show the choosing principle of anti-floating design method and the calculative process of whole and partial anti-floating design method.The calculative process of the pile raft foundation was also demonstrated.
