本工程为南京某（36层）高层住宅楼的基坑支护结构及监测系统设计，先采用水土合算计算支护桩所受的主动土压力和被动土压力，再采用等值梁法计算支护桩的弯矩并进行支护桩的配筋计算；支撑形式采用角部角撑和中部对撑，采用简化计算的方法进行内支撑的内力计算并进行配筋；基坑通过设置止水帷幕达到止水的目的，降水分为疏干降水和承压降水，分别计算；运用理正深基坑设计计算软件分别进行基坑单元计算和整体计算，用于和手算进行比较；由于本工程基坑属于一级基坑，所以设计了严密的监测系统，保证工程安全。最后总结了本次毕业设计的成果。 9887

Building (36-storey) in Nanjing - Foundation Pit Supporting
Structure and Monitoring System Design
Abstract
This project is the foundation pit supporting structure and monitoring
system design of a Nanjing (36 storeys) high-rise residential building,
firstly, use soil and water cost-effective computing method calculate
active earth pressure and passive earth pressure of support piles.
secondly, use equivalent beam method calculate the retaining pile bending
moment and the supporting piles reinforcement; the form of the support use
corner gusset and central support, use simplified calculation method
calculate the internal force of supports and reinforcement; the pit achieve
the purpose of sealing by setting the sealing curtain, the precipitation
is pided into dewatering precipitation and pressure precipitation and
calculated separately; use deep excavation design software calculate pit
unit and the overall structure; in this project, the pit is first level
pit, so the design of a monitoring system is rigorous to ensure the safety
of the project. At last, summarizes the results of the graduation project
in the end of the article.
Keywords: Foundation pit supporting structure; monitoring system;
support; precipitation
