Deformation Monitoring And Analysis Of Pile-Anchor Supporting Structure

With the rapid development of urban construction, the emergence of the deep foundation pit engineering is becoming more and more common. Pile and anchor combined support structure as s common form of support of deep foundation pit engineering. It is important of practical significance to in-depth study of pile-anchor combined support structure and its impact on the surrounding environment. This kind of composite supporting structure has good benefit about social and economic, and the broad application prospects.In this paper, according to the actual excavation engineering, the design scheme, the selection of design parameters and the calculation results of condition under the software are described in detail. With the design requirements and the monitoring technology standard of building foundation pit engineering, the supporting pile made the experiment on the pile shaft deformation, made the deformation monitoring on the top of pile, made the subsidence monitoring experiments about the building around the settlement. Using the mapping method and the tabular method to statistic the data for observation. Vividly described the variation about the deformation of the supporting structure and surrounding buildings for the condition of the progress and the change of time. Comparative analysis the results of software designing and actual monitoring results to make a conclude of pile anchor structure, to provide a reference for the future of the development about the theory of pile anchor and the design of supporting structure.It is play a vital role about the information constructure and the dynamic management of risk in the whole process of foundation pit supporting. Only the design, constructure and monitory three aspects closely cooperate with up and realize the information constructure, in order to reduce the probability of accidence about foundation pit engineering.
