Design of Foundation Pit Support Project Close to the Subway

Abstract:

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.
