A Novel Approach for Determining Pile Spacing considering Interactions among Multilayered Sliding Masses in Colluvial Landslides

摘要: It is reported that there are many colluvial landslides with multilayered sliding masses; however, previous studies of the pile spacing stabilizing piles mainly focus on single-layered mass, which may lead to design errors for spacing. Consequently, paper presents a novel method determine considering interactions masses in landslides. Based generalized landslide model, equations calculating stability coefficients were improved by examining among masses. An accordingly model double-layered was established finite differential method. The distribution vertical driving force and horizontal loading between adjacent studied based landslide. A maximum minimum deduced soil arching effect reasonable obtained cost performance piles. calculational process, determines optimal masses, shown Bazimen variations affected various soil-layer sequences illustrated employing model. calculation results indicate positively correlated depth resistance force. Effectiveness significance presented proved through verify using numerical modeling approaches.
