摘要
福州仓山区某超深地下室在深厚淤泥中采用静水浮力释放系统设计与施工。该系统是基于基坑止水帷幕插入深度和淤泥渗透慢特性实现的,为一种较先进的绿色设计技术。合理设计此释放系统,可有效降低抗浮水位,可充分节约基础造价、减少施工工期。基此,文章探讨了该基坑止水帷幕作用、渗流水量计算、排水系统设计、应急措施等。
This paper discusses the design and construction of hydrostatic buoyancy relief system for an ultra-deep basement in Fuzhou with an example. The system is based on the insertion depth of water-proof curtain and the slow permeability of silt. The function of curtain for cutting off drains,the calculation of seepage water,the design of drainage system and emergency measures are discussed. Reasonable design of this relief system can effectively reduce the anti-floating water level,fully economize the cost of foundation and reduce the construction period. It is an advanced green design technology.
