Soil Rock Slope Reinforced By Anti Slide Pile Observation And Effect Analysis

This paper to Heda highway the three tenders YK24+785-90 subgrade landslide is the research background of the thesis, with field monitoring data combined with the numerical simulation and analysis, by in large section reinforced concrete anti slide pile internal binding polyethylene measuring method of inclined tube, to monitor the anti sliding lateral horizontal displacement of the pile in the process of construction. Will be buried in the surface of reinforced concrete anti slide pile is regarded as a beam on elasticfoundation, applied arts Le assumption, the differential equation of the elastic curve is solved, eventually leads to the reinforced concrete anti slide pile in front of the pile resistance, shear force and bending moment of the pile side and angle etc.; Using MIDAS/GTS numerical simulation software of slope in the natural state, after excavation and construction of anti slide pile three conditions of displacement deformation and shear deformation are simulated,obtained the displacement deformation and shear deformation under the three conditions of the, and coefficient of the stability of slope. It is proved that the construction of anti slide can effectively control of landslide deformation, greatly improve the safety coefficient.in cast-in-place reinforced mixing concrete anti slide pile, measured by the inclinometer of pile lateral displacement is seen as the pile bending deformation parameters of steel and concrete, using MATLAB software package deformation parameter import data fitting and to calculate steel mixed anti slide pile bending moment, shear force and anti sliding force. Finally this method is applied to Heda highway landslide anti slide pile in the construction process of deformation monitoring, use as a judge on anti slide pile with reference to the evaluation of the effectiveness of, and for steel mixed anti slide pile design to provide a reliable basis.
