The Study Of Three-dimension Visualized Monitoring And Controlling System For The Excavation Bracing System

The utmost important problem of the foundation-pit is that the prevention and treating of the foundation-pit accident during the excavate period. What's more, it is a key problem in the deep foundation-pit engineering practice. This paper is meant to research and develop a entirely different construction technique, which is a new strutting and monitoring system used in excavation constructed practice. The system could not only monitor the excavation state, but also provide the dangerous state alarm and instruction of the treating method, which is necessary to guarantee the safety of the excavation and prevent the excavation accident.On the base of former study, the development and characters of exaction engineering was expound perspicuity firstly. Aiming at the status and existing questions of the excavation engineering accident, the factors of controlling the formation of the excavation was analyzed generally by referencing to the abroad and internal articles, and promoted the flexible strut system that could control the strut force automatically. The mathematic model of the strut system was formed on the base of analysis the modeling method at the present time. And the mathematic software was built on the MATLAB platform.Secondly, depending on the LabVIEW, ActiveX and OpenGL computer techniques, a monitoring system of foundation excavation was founded, which is integrated with data automatical collection, treatment and analytical evaluation, and automatically displaying the state of excavation by 3D visible simulation technology. And it takes important meaning to restrict the strain, to improve the safety of the excavation and protect the surrounding environment.Thirdly, the reasons of the excavation engineering accidents was analyzed, and the method of preventing and treating of excavation accidents that set up a process control and security early warning system of excavation engineering using the expert prediction system.At last, through the practice of the real project of excavation engineering using the Three Dimension Visualized Excavation Monitoring System, combining the...
