一种圆筒形地下粮仓的抗浮设计

摘要

以一种大直径圆筒形地下粮仓工程为背景,根据当地地质条件,对目前的抗浮下拉法、配重法、抗浮梁压顶法等抗浮措施进行了比较分析.研究发现:抗浮下拉法、配重法等不利于建筑构造的防水、施工等,影响结构安全；抗浮梁压顶法有利于工程的防水处理,是一种比较理想的抗浮措施.结合相关规范,给出了抗浮梁压顶法的设计方法.结果表明,该方法能较好地解决地下粮仓的抗浮问题.%Based on large-diameter cylindrical underground granary project,we compared and analyzed the existing anti-floating pull down method,balanced weight method,and anti-floating beam press roof method,according to the local geological conditions.The results showed that the anti-floating pull down method,the balanced weight method and the like could influence the structural safety due to the bad impacts on the building waterproof processing,construction and the like.The anti-floating beam press roof method was good to project waterproof processing,and was the ideal anti-floating measure.With reference to related standards,we put forward the design method of the anti-floating beam press roof method.The calculation result showed that the method could well solve the anti-floating problem of the underground granary.
