摘要:
为了研究高水位地区地下结构抗浮问题,提出在地下结构基础底板下方设置具有专利技术的S型排水DM(drainage mat)地下结构主动抗浮措施,采用数值分析深入研究地下结构主动抗浮工作机制,制定了地下结构主动抗浮措施的设计原则和计算方法,并应用于厦门和昌中心地下结构抗浮工程中。研究表明,地下结构主动抗浮措施消减了基础底板下方土体孔隙水压力,达到地下结构抗浮目标,节省了工期和造价,工程应用前景广阔。
关键词: 地下结构, 主动抗浮, 孔隙水压力疏导调节, S型排水
Abstract:
The antiuplifting of underground structures in high groundwater level area is very important; as a result, Styped drainage mat set under basement slab of underground structure is proposed. The working mechanism of active antiuplifting technology for underground structures is numerically simulated and analyzed. The design principle and calculation method for active antiuplifting technology for underground structures is established and applied to foundation of Hechang Center in Xiamen. The study results show that the pore water pressure of soil under basement slab of the foundation of underground structure has been reduced; the construction cost has been reduced and the construction schedule has been shortened by adopting active antiuplifting technology.
Key words: underground structures, active antiuplifting, hydrostatic uplifting pressure relief system, Styped drainage mat
