Abstract:At present,all kinds of large-scale construction projects in China put forward strict requirements on the design of pile foundations,and the lateral bearing analysis of piles is a prominent problem. A new differential equation for the pile deflection containing the side frictions was established based the conventional method of analysis to the laterally loaded piles. The fm - method of calculating the lateral bearing capacity of piles under small deformation was proposed with the consideration of friction effect. In order to validate the proposed method,the corresponding Matlab program and some examples of laterally loaded piles were used. The effectiveness of the method was reviewed. Additionally,the comparison of the calculated results from the original m-method and the proposed fm -method was made. The influence of the scale effect on the lateral bearing characteristics of pile foundations was obtained.
