Foundation Pit Deformation Control of a Pharmaceutical Factory Extension Project in Beijing
A pharmaceutical factory building in Beijing is in use.Extension is required to increase production capacity.The foundation pit of the extension project is close to the existing factory building and only 0.8-1.4m away from the original factory foundation.In order to reduce the influence of deformation and vibration on the existing workshop,it is necessary to strictly control the displacement,settlement and vibration of the newly excavated foundation pit.Many measures have been taken during the design and construction of the project,which effectively avoid the above-mentioned risks and control the deformation well.In this paper,the support design is checked by the Lizheng Deep Foundation Pit software,and the calculation results are verified by the actual foundation pit displacement monitoring results.
