In the upper part of pit, the internal forces of simulated values of the soil nails is smaller than the measured value, because the profile is located next to the material library, which produce a certain amount of additional load; in the toe of pit, the slope soil nails internal force is smaller than the measured value, because in the model, we do not consider the impact of groundwater.
