Design And Numerical Simulation Of Deep Foundation Pit Engineering

With the development of our national economy, the city infrastructure construction in full swing, the foundation pit engineering more and more appear in large and medium-sized city, foundation pit engineering will inevitably face a series of problems such as the design and construction monitoring. Relying on a project example, engineering outline on the ground and on the basis of the analysis and study of the engineering geological conditions, combined with the characteristics of foundation pit supporting is commonly used in China and using range, on the basis of the choice of the type of foundation pit supporting factors, the principle, selecting the best supporting scheme for the projects. Use of reason is the software of the deep foundation pit supporting structure design, get the change law of internal force and displacement of supporting structure, it is concluded that the pile and anchor cable reinforcement concrete design parameters, and according to the design results are excavation and supporting. Foundation pit design work is completed, in accordance with the principle of foundation pit monitoring scheme, monitoring and other requirements for real-time monitoring of foundation pit excavation process and finishing monitoring data. The foundation pit is simulated using FLAC3 D analysis, horizontal displacement, vertical displacement, stress distribution law of change. The last of the foundation pit is design value, FLAC3 D software, comparing the simulation value, real-time monitoring of the three reveals the change rule.
