1工程概况辽宁省盘锦市某化工有限公司14万t/年ABS扩建项目,该项目中有一个35m×20m×8m的地下水池。因地下水位较高(最高静止水位在2.2m左右),设计该地下水池的桩基础时,须考虑水池的抗浮问题,设计要求单桩竖向承载力fk=1 000kN,单桩抗拔力Nk=200kN。勘察场地自然地面以下 1 Project Overview Panjin City, Liaoning Province, a Chemical Co., Ltd. 140,000 t / year ABS expansion project, the project has a 35m × 20m × 8m underground pool. Due to the high groundwater table (the maximum resting water level is about 2.2m), the anti-floating of the pond shall be considered when designing the foundation of the underground pond. The design requires that the vertical bearing capacity of single pile is fk = 1000kN, Nk = 200 kN. Survey site natural ground below
