Analysis of the Lateral Force on Stabilizing Piles in c-φ Soil

Abstract

In the past, the lateral force on stabilizing piles has been studied by many researchers. In this study, the lateral force loading on stabilizing piles per unit thickness is analyzed in a semi-infinite c-φ soil ground (φ > 0, c > 0). The soil arching effects between two neighboring piles are considered. A new formula is proposed to estimate the lateral load acting on the stabilizing piles. When the proposed approach is applied on some kinds of c-φ soil, an invalid value would be obtained on the failure plane. However, the invalid value can be ignored since it has little impact on the solution. The in situ observed tests from the literatures are introduced to validate the proposed approach. The comparison charts illustrate that the prediction from the proposed approach shows a better agreement with the test results comparing with the solution from plastic deformation theory.
