| Abstract: | The bearing behavior and reinforcement mechanism of a composite bolt pile was studied through numerical calculation with the FLAC soft. The composite bolt pile was successfully used in several ground-reinforcing engineering. The results of numerical simulation and engineering monitoring show that the bearing behavior of the composite bolt pile is improved in comparison with a single bolt pile, the effective factor and bearing capacity of the pile are obviously enhanced. |
