Abstract：
It is usually difficult to use ordinary excavation method in complex deep and thick silty foundation. A practical engineering case was introduced to analyze the construction characteristics and difficulties and discuss the construction process, key construction point, safety techniques and control measures of layered backfilling excavation technique. Difficulties in construction under deep and thick silty foundation were effectively overcome to guarantee the smooth foundation pit excavation, providing references for similar projects.
