坡地建筑地下室利用高差的抗浮设计研究

Study on anti-floating design of the slope buildings basement by using elevation difference

坡地建筑利用场地高差进行排水疏导设计,降低了抗浮设计水位,能够节约材料和造价,是一种很好的绿色技术设计。本文分析和探讨了排水疏导设计的组成内容及必要性,排水疏导设计是一个需要考虑建筑使用寿命期内安全使用的系统设计,它包括地下室周边及底板的疏排水系统、与市政管网排水系统的连接、日常检查与管理维护、监测预警系统、应急抽排水措施等内容。

The drainage design of the slope buildings basement using the elevation difference of the site can reduce the anti- uplift water level and save materials and cost,it’s a kind of very good green technology design. The content and the necessity of drainage design are analyzed and discussed in this paper. The drainage design is a systemic design that should keep the structure safety in the period of the service life,and it is including the drainage system of the basement and foundation slab,the connection to the municipal drainage pipe system,the daily check and maintenance management,the monitoring and early warning system and the emergency measures of the suction drainage.
