Boundary value problem for analysis of portal double-row stabilizing piles

This paper presents a new numerical approach for computing the internal force and displacement of portal double-row piles used to stabilize potential landslide. first,the new differential equations governing the mechanical behaviour of the stabilizing pile are formulated and the boundary conditions are mathematically specified. then,the problem is numerically solved by the high-accuracy runge-kutta finite difference method. a program package has been developed in matlab depending on the proposed algorithm. illustrative examples are presented to demonstrate the validity of the developed program. in short,the proposed approach is a practical new idea for analyzing the portal double-row stabilizing pile as a useful supplement to traditional methods such as fem. © 2013 cheng huang.
