Abstract：
The discharging well foundation pit of Beijing Laiguangying West Bridge water accumulation treatment project is adjacent to existing building, so surface soil stratum strengthening plus grid steel frame plus mesh pneumatically placed concrete plus steel tube support combination measure was adopted during foundation pit excavation. Support construction was carried out according to supervision information and dynamic management was formed to reduce the influence of soil disturbance on existing buildings due to excavation. Foundation pit deformation and settlement of adjacent buildings were controlled within the allowable range.
