Study on Proportioanl Relation-ship of Lateral Bearing Capacity of Batter Pile by Model Experiments

Some researches indicate that the bearing capacity of negative battle pile is less than that of positive batter pile under free pile head. But the head of the engineering pile is used under some constraints. So the lateral bearing capacity is studied under different batter and different constraints at pile head by model experiments made by ourselves. The analysis indicates that (1) the lateral capacity of the negative batter pile decreases as the batter angle decreases when the pile head is only translational, (2) the lateral capacity of the negative batter translational pile is more than that of the positive batter free pile and (3) the proportional coefficients of the bearing capacity are provided under the experiment conditions.
