Displacement And Numerical Simulation Analysis Of Pile-anchor Bracing Structure

The pile anchor support structure since the1980s, application and development of a new type of supporting structure, has been widely applied in the deep foundation governance. Landslide. At present, domestic and foreign scholars pile pile anchor support structure under the external force displacement of insufficient.The Foundation Pit project inclinometer test to collect experimental data, to map out the various conditions supporting piles displacement curves; foundation pit excavation using finite element software ADINA simulation to support the process of simulation results; experimental results and simulation results compared, and the following conclusions:(1)Displacement analysis of the situation through the foundation pit supporting structure of the different operating conditions, it is reasonable arrangements for each operating mode support, such as the excavation depth of each step arrangement, bolt arrangement is the need to increase the temporary support arrangements.(2)Crown beam monitoring results of the comparison of experimental results through the pile inclinometer displacement of the pile and crown beam displacement is basically the same.(3)By comparative analysis of pile displacement with the crown beam displacement, we can see the collaboration between the pile-anchor structure charged to protect pile and crown beam.(4)Through the finite element software ADINA simulation results and inclinometer test, displacement monitoring results compared to verify the finite element software ADINA simulation results and inclinometer test, displacement monitoring results.
