随着国家城镇化推进速度的加快,城市土地渐趋于紧张,城镇化的进程建设需要大量的高层与超高层建筑,而对于此类建筑,基坑支护与其密不可分,且由于建筑功能上的需要高层、超高层建筑通常设置数层地下室,由此在施工阶段对深基坑支护方案提出了更高的要求。本文分析现有较为成熟的深基坑支护方案的技术特点和适用条件,通过比较各基坑支护方案的安全性、经济性和适用性,提供选取合适的深基坑支护方案的建议。以方便工程师设计安全合理、经济性好、满足施工要求的基坑支护方案。
With the accelerating urbanization in the country, urban land tends to be tense and a large number of high-rise and super-high-rise buildings are required in the process of urbanization. However, for such buildings, the foundation pit support is closely linked with the building function The need for high-rise, high-rise buildings usually set several basements, which in the construction phase of the deep foundation pit support program put forward higher requirements. In this paper, the technical features and applicable conditions of the existing deep foundation pit supporting schemes are analyzed, and the suggestions of selecting appropriate supporting schemes for deep foundation pit are provided by comparing the safety, economy and applicability of each retaining plan . To facilitate engineers to design safe and reasonable, good economy, to meet the construction requirements of the pit support program.
