| 摘 要： | 某工程在黄海高程-10.2~-10.8 m处有承压水存在,由于挖土卸荷作用,使基底上覆土重力小于承压水浮力,为防止基坑因突涌而失稳,对基底采用了灌浆固结施工措施,保证了基坑的稳定并缩短了工期。

| Abstract: | In construction of a project,there exists the confined water at(-10.2)-(-10.8) m of Yellow Sea Datum.Due to the unloading incurred by excavation,the weight of coverage soil on foundation base is less than the buoyancy of confined water.In order to prevent instability of foundation pit caused by drainage of confined water,consolidation grouting measure is adopted for the foundation base,so that the foundation pit is stabilized and the construction period is shortened. |
