Construction Control Technology of Offshore Water-rich Sand Layer near Building Foundation Pit
In order to ensure that the surface settlement value of offshore water-rich sand layer excavation does not exceed the allowable value of housing construction within the influence range,this paper compares and analyzes the excavation,support,and precipitation plans through modeling and simulation calculations,combining calculated data with actual measurements.It proposes a monitoring and measurement method for excavation of foundation pits in water-rich sand layers near buildings,increasing the mud density for wall protection,multiple water blocking and waterproofing measures,and precipitation measures.The technical difficulties encountered during construction have been successfully solved,with the aim of providing experience and reference for similar projects.
