摘要

针对基坑紧邻河道、周边情况较为复杂的情况,结合工程实际,从基坑围护设计、支撑优化、基坑降水、土方开挖、基坑临时支撑施工等几个方面介绍了实际工程中所采取的技术措施。工程监测数据表明,基坑变形均小于设计报警值,基坑施工一直处于安全可控状态。充分证明了工程所采取的技术措施切实可行,也为其他类似工程的施工提供借鉴。
In view of the foundation pit adjacent to river and complex surrounding situation, combined with the engineering practice, the technical measures taken in practical projects is introduced from the aspects of foundation pit support design, support optimization, foundation pit dewatering, soil excavation, and foundation pit temporary support construction, etc. Engineering monitoring data shows that if foundation deformation is less than design alarm value, the foundation pit construction has been in safe and controllable state. It fully proves that the engineering technical measures are feasible and can provide reference for other similar engineering construction.
