Abstract: The bending behavior of double-row stabilizing plies is associated with the constructional time delay (CTD), which can be defined as the time interval between the installations of the front stabilizing pile and the rear stabilizing pile. This paper investigates the effect of CTD on the bending moments of double-row stabilizing piles and a method for determining the optimal CTD is proposed. The stabilizing pile is modeled as a cantilever pile embedded in the Winkler elastic foundation. A triangular distributed earth pressure is assumed on the pile segment in the sliding layer. The front stabilizing pile and the rear stabilizing pile are connected by a beam with pinned joints. The analytical solutions of bending moments on the front and the rear stabilizing piles are derived and the accuracy of bending moment solutions is validated by comparing the tensile strain measured from the Hongyan landslide project, Taizhou, Zhejiang, China. It is concluded that CTD has a significant influence on the bending moments of double-row stabilizing piles. An optimal CTD can be obtained when the maximum tensile stress in the front stabilizing pile is equal to that in the rear stabilizing pile, which is 1.4 months for the Hongyan landslide project.
