Simplified calculation method of horizontal displacement of row piles and soil nailing composite supporting structure
For the row piles and soil nailing composite supporting structure,a simplified calculation method of the horizontal displacement of the structure considering the influence of the construction process was established by the incremental method.According to the stress and deformation mechanism of the structure,the basic assumption of deformation coordination of soil nailing head and row pile in corresponding position was introduced in the calculation method.Moreover,the construction conditions of the excavation step were also considered.The engineering applicability of the horizontal displacement calculation method was verified by the comparison of the calculation results and the monitoring results of the project.
