摘　　要：紧邻地铁基坑支护必须确保地铁运营的安全,具有难度大、支护安全储备高的特点。结合广州市林和村改建项目A地块临近地铁基坑支护工程实例,通过三维数值分析计算,基坑位移、稳定性均可满足设计要求。并对薄弱点进行加强监测。最后通过实测值复核计算值,实测值基本控制在计算值范围内。The safety of subway operation must be ensured in the construction of foundation pit support project close to the subway with great difficulty and high safety margin.This paper describes an engineering practice of foundation pit support close to the subway,by the three-demensional numerical analysis,the displacement and stability of the excavation met the design requirement and the weak points were mainly monitored.According to the check calculation on measured values,the measured values were controlled in the range of calculated values.
