系统地介绍了某纯地下裙房抗浮验算不足时采取的结构解决方案。通过多方案的可行性比较和成本分析,采用增减相结合的设计方法,即在增加结构自重的同时,通过设置盲沟来降低地下水位,使自重和浮力达到平衡。
This paper systematically introduces the structural solution adopted in the anti-flooding calculation of a pure underground podium. Through the feasibility comparison and cost analysis of multiple schemes, the design method combining the increase and decrease is adopted. That is, while increasing the self-weight of the structure, the blind water level is lowered to lower the water table and balance the self-weight and the buoyancy.
