昆明市某基坑支护工程方案研究

Research on Supporting Project of a Foundation Pit

文中以昆明市某基坑支护工程方案为案例,首先介绍了研究区的地质概况,依次从设计标准、降排水方案、锚索试验方案进行了详细阐述。认为开挖过程中,应对施工过程中出现的异常情况及时整改,并合理调整施工组织设计和土方开挖方案。施工单位在进行施工组织设计时,需对支护结构施工方法、质量控制要求及土方开挖方案进行仔细研究,预先做好抢险预案并提前准备好抢险物资,确保基坑顺利施工。

Taking a foundation pit supporting project in Kunming city as a case, this paper first introduces the geological situation of the study area, and then expounds the design standard, drainage scheme and anchor cable test scheme in detail. It is considered that the abnormal situation in the construction process should be rectified in time and the construction organization design and earthwork excavation scheme should be adjusted reasonably. Construction units in the construction organization design, the construction method of supporting structure,quality control requirements and earthwork excavation scheme carefully studied, in advance to make emergency plan and prepare emergency materials, to ensure the smooth construction of the foundation pit.
