The Research On Deep Foundation Pit Excavation Deformationwith Support Bythe Pile Anchor And Information Construction

Recently , we were called for to catch up with the fast development of economic construction with the increase of national income and reduction of urban land, many large, very large civil engineering projects came into being, such as the Qinghai-Tibet Railway project, the Olympic project, the South river tunnels to the North, subway and so on. These constructions of large projects were attended by the world. Along with these high, big, heavy, deep structure, the design and construction of the field of deep foundation pit have become the difficulties to solve, Select the design supporting properly and construction program. For this situation, deep foundation pit in the industrial park were monitored and analysis, such following aspects were discussing:1) By discussing the background and development course of deep foundation pit engineering , make the study on current conditions and deformation theory to certain extent.2) Prestressing calculation method of deep foundation pit.3)To describe the environment, climatic , engineering geology, hydrogeology, construction , and temporal effect the deformation of deep foundation pit by constructing the deep foundation pit, monitoring and information feedback, analysis the soil- Nail wall and the pile anchor system's deformation mechanism, play time to forecast the danger during the foundation construction occurred,which motivated to take emergency measures to avoid accidents. Also verify the design of foundation pit for future design, construction and accumulated valuable.4) To summary the whole article, pointing out that deep foundation pit construction of the whole process is an indispensable is and a information center. In addition, look forward to development of deep foundation pit, and propose the questions shall be noticed, combined with this paper in future research concern.
