Deep Foundation Pit Support Scheme Optimization And Applications

With the rapid development of our national economy, construction technology andconstruction level rise ceaselessly, the various large and medium-sized city has emerged alarge number of high-rise and super high-rise building, These buildings design buried depth ofthe foundation increases ceaselessly, make the building foundation construction phase of thedeep foundation pit safety has become a new and urgent problem.Deep foundation pit engineering is a complex, highly integrated systems engineering,involves having mechanics, soil mechanics, theoretical foundation, foundation treatment, insitu test and other disciplines of knowledge, but also affected by site conditions, geologicalconditions, the surrounding environment, climate change, economic conditions and otherfactors.。This paper introduces the current application in the construction of foundation pitsupporting basic form, including the cantilever retaining, supporting the support, pullinganchor, combined support in various. And to the Chaoyang Square project of foundation pitsupport design as an example, how to suit one’s measures to local conditions, taking variousfactors into consideration, on supporting scheme of deep foundation pit design and rationalselection, and ultimately determine the reasonable supporting scheme. Through a engineeringcase study, obtained the foundation pit support technology applied to the industry in3conclusions, future prospects.
