Research On The Retaining And Protecting For Deep Foundation Excavation In Huanghua Port Overturned Room Corridor Application Of The Diaphragm

With the rapid development of the urbanization building and the port, the pace of development in terms of quantity and height has been reached an unprecedented pace.So the depth of excavation is gradually increasing, for retaining and protecting for deep foundation excavation bracing works by increasing world attention, including the diaphragm in retaining and protecting for deep foundation excavation is applicated more widely.This paper was combined the diaphragm of applicationg in Huanghua Port overturned room corridor of deep retaining and protecting, for retaining and protecting for the diaphragm structure of the sensitivity analysis of the characteristics.Through the actual situation on the foundation pit,excavation,bracing system,monitoring all aspects of design was calculated. Considering the impact of the construction calculation and basing on results of the calculation of diaphragm is guided in the foundation pit construction and for the bracing system design and construction, and carries on the analysis to the diaphragm construction's quality control and the preventive measure.This paper was designed optimization the retaining and protecting system in the Huanghua Port overturned room corridor of deep retaining and protecting, changing the bracing system of program structure of tender form, bracing system materials, expanding the earth excavation face, reducing the bracing system material, shortening the duration, while was reduced the project costs. So in such areas as of the bracing system for structural optimization of the design were got good value for economical available, to provide reference for future similar engineering project.
