| Abstract: | In order to understand goodly the reinforcement mechanism of the pile-anchor and soil nailing combined structure,optimal design and numerical simulation for a large deep excavation pit with pile-anchor and soil nailing in Zhengzhou city were done,the process of pile-anchor and siol nailing combined supporting was numerically simulated by the software FLAC3D,the displacement field of the pit and the change of the stress of siol-nail-anchor structure cell were analyzed.The simulation results were basically consistent with the design calculations results.The results of numerical simulation had effectively guidance to design and calculate,and in-site construction process. |
| Keywords: | numerical simulation structure element pile-anchor and siol nailing combined structure |
