In this paper, through the analysis of miscellaneous fill slope horizontal displacement of supporting structure and the vertical displacement monitoring results, the simulation results are compared and analyzed with FLAC3D software, verify the support form the deformation in the controllable range, the actual monitoring data and simulation results in the difference between the standard allows range, fitting deformation curve can be used as a conventional deformation monitoring based on integral deformation analysis, advanced demonstration of engineering construction scheme optimization.
With the improvement of technology, the dynamic monitoring has become an essential modern engineering construction link, in the process of effective data analysis, it not only provided a fundamental guarantee for the engineering safety early warning, but also provide a good calculation basis for the similar engineering design.
