Research on bearing capacity of inclined pile under vertical load
Inclination of piles may occur due to different reasons. How to determine the bearing capacity of inclined piles is a tough problem in practice. Field load tests on inclined piles, the required characteristics of soil for FEM analysis were obtained to conduct numerical analysis. The bearing capacities of piles with different degrees of inclination under different soil conditions were studied. It was shown that the settlement of piles was obviously influenced by the soil conditions, and that under the same vertical load the settlement of piles with the degree of inclination no more than 5 percent was even smaller, but the settlement of piles with the degree of inclination more than 5 percent increase obviously. With the inclination increases its bearing capacity is decreased obviously, thus the degree of inclination is the main factor of which control the vertical bearing capacity of inclined piles.
Analysis of batter pile under arbitrary inclined loads in semi-infinite solid
An elastic analysis of batter pile subjected to inclined load was presented. The problems formed some integral equations developed from Mindlin's analysis for a point load embedded in a semi-infinite ideal elastic half space. Using numerical method and Gauss integration technology, the solutions of pile displacement were obtained. Two typical cases, the different batter angle of pile subjected to the same vertical load and the vertical pile subjected to different inclined load, were analyzed. The bearing capacity of the piles is found to depend on the load inclination and pile batter angle. The allowable settlement of pile head is suggested and vertical pile can bear load with inclination of less than 10°, and batter pile bearing vertical load can be angle of less than 10°.
