Monitoring and calculation of anti-slide piles internal force

The anti-slide pile has been widely used in the treatment of landslide,but research on the monitoring of the anti-slide pile is not intensive.Based on the model of Winkler elastic foundation beam,the reacting force of the rock can be educed from inclinometer reading,and then residual landslide thrust on anti-slide pile is estimated using mechanics equilibrium principle.Monitoring the stress of reinforcing steel bar,the moment of the section where setting the strain gauge can be obtained.Assumption that the distribution function of the residual landslide thrust is a quadratic polynomial function,we can obtain the function based on the calculation results.Once we ravel the loads of the anti-slide pile,we can deduce its moment and shear diagram. Compared with the designed value of internal force,we can infer the effect of the anti-slide pile,and this can supply evidence for the further treatment of landslide.
