Textual research content include there in after several Aspect:(1) Generalizing the current research status on the design and construction of the deep foundation pit in the world,and also summarizing the calculating models and the theories,and giving a introduction of the arched row pile supportin

Taking the tunnel RK2+280～+300 section in a foundation pit as an example,this paper introduced a monitoring program for the pile-bracing system,and carried out some monitoring data, including the horizontal displacement and displacement at the top of the pile pit structure,surface settlement of surrounding buildings,supporting ability.
