福州火车北站改扩建某大型安置区岩土工程实例分析

Analysis on geotechnical engineering of a large resettlement area reconstructed and expanded by Fuzhou North Railway Station

根据福州火车北站改扩建某大型安置区建设工程实例,文中针对山前平原场地软土地层与强、中风化带岩层交替分布的复杂地质条件,并结合周边环境条件,对该项目岩土工程基坑支护设计方案的选取进行详细比较分析。根据基坑监测数据结果表明,该工程因地制宜所采取的深基坑支护方案有效地保证了支护体系的稳定及周边环境的安全,该支护方案安全可靠、经济合理,可作为该地区类似场地条件下的深基坑支护设计及施工参考借鉴。

According to the construction project of a large-scale resettlement area reconstructed and expanded by Fuzhou north railway station,this paper analyzes in detail the selection of foundation pit support design scheme of geotechnical engineering of the project according to the complex geological conditions of alternate distribution of soft soil layer and strongly and moderately weathered rock layer in piedmont plain site,combined with the surrounding environmental conditions.According to the monitoring data of the foundation pit,it shows that the project is made in accordance with the local conditions The supporting scheme of the deep foundation pit is suitable to ensure the stability of the supporting system and the safety of the surrounding environment.The scheme is safe,reliable,economic and reasonable,which can be used as a reference for the design and construction of the deep foundation pit under similar site conditions in this area.
