摘　　要：某项目地下室主体结构已施工完毕,经过连夜暴雨后,该区域地下室抽水不及时,且地下室顶板尚未覆土,造成部分地下室结构上浮。传统一般采用底板开泄水孔泄压、向地下室灌水加压进行应急处理,采用柱周包钢、粘贴碳纤维、植筋加大截面法加固,缺乏综合性的处理方法。为此,论述地下室上浮的系统性处理方法,总结了应急处理、地基处理、顶板处理和产生不同破坏的8类柱的加固处理方法,取得了理想的效果。The main structure of the basement of a project has been completed.After the overnight rainstorm,the basement in this area did not pump water in time,and the roof of the basement has not been covered with soil,causing part of the basement structure to float.Traditionally,the bottom plate is used to open a drain hole to relieve pressure,and the basement is filled with water to pressurize for emergency treatment.The method of wrapping steel around the column,gluing carbon fiber,and planting steel bars to increase the section is used for reinforcement,which lacks a comprehensive treatment method.For this reason,the systematic treatment method of basement floating is discussed,and the emergency treatment,foundation treatment,roof treatment and reinforcing treatment methods for 8 types of columns with different damages are summarized,which have achieved ideal results.
