以深圳地铁一期工程金田站为例,针对地下三层侧式站台车站整体抗浮安全和水浮力作用下的结构受力问题,运用地下水渗流理论定量计算了倒滤层消浮的泄水量和影响范围,并对不同抗浮方案的结构受力、变形进行了计算和对比分析,最后通过综合比选确定了经济合理的抗浮方案。
Taking the Jintian Station of Shenzhen Metro Phase I project as an example, aiming at the problem of the structural resistance under the anti-floating safety and water buoyancy of the underground three-story station platform, the groundwater seepage theory was used to quantitatively calculate the discharge volume Influence range, and the structure of different anti-floating program stress and deformation were calculated and compared, and finally by comprehensive comparison and selection to determine the economic and reasonable anti-floating program.
