Abstract Batter piles are widely used in geotechnical engineering construction. Observations regarding the performance of batter piles in seismic hazards are controversial, and few studies have evaluated batter piles in liquefiable and laterally spreading ground. Three centrifuge experiments were performed to gain a better understanding of the performance of batter piles in liquefiable ground and to reveal the influence of the overlying nonliquefiable layer on the batter pile foundation design. The results reveal that for symmetrically placed batter piles, the bending moment of the front pile is greater than that of the rear pile, as a result of the liquefaction-induced lateral deformation in all three cases, and the bending moment reaches its maximum value at the middle of the pile. The presence of the overlying nonliquefiable dense sand layer reduces the potential for liquefaction and lateral spreading of the underlying ground, the settlement and bending moments of the batter piles.

侧向铺展土中斜桩基础的离心建模

摘要 击打桩在岩土工程建设中应用广泛。关于斜桩在地震灾害中的性能的观察是有争议的，很少有研究对可液化和横向扩展的地面中的斜桩进行评估。进行了三个离心机实验，以更好地了解斜桩在可液化地基中的性能，并揭示上覆的非液化层对斜桩基础设计的影响。结果表明，对于对称放置的斜桩，前桩的弯矩大于后桩，这是三种情况下液化引起的横向变形的结果，弯矩在以下位置达到最大值。堆的中间。
