摘要
在实际工程中,基坑支护方案的选择直接关系到工程造价、施工进度及周围环境的安全。本文综合考虑基坑开挖深度、地质条件及周边环境等特点,采用灌注桩+二道钢筋混凝土内支撑进行支护,内支撑体系采用环撑、对撑结合角撑的平面布置方式,支撑标高结合地铁车站楼板标高进行设置,最终确保了基坑土方开挖,达到了工期施工的要求,也有效地保护了基坑周边地铁车站及周边环境的安全。
In practical engineering, the selection of foundation pit supporting scheme is directly related to the cost of the project, the construction schedule and the safety of the surrounding environment Considering the excavation depth, geological conditions and surrounding environment of the foundation pit, the scheme with bored piles and 2 layer internal reinforced concrete support system was adopted The support system includes ring support, symmetry support and angle support The supporting elevation is equal to the elevation of the subway station floor Finally, the construction requirements of excavation and construction of the foundation pit are effectively ensured, and the safety of the subway station and the surrounding environment around the foundation pit is effectively protected.
