目前已有土‑挡土墙动力相互作用的理论分析方法通常把墙后土体假设为均质土,很少能考虑层状土对挡土墙动力响应的影响。已有研究表明,挡土墙后层状土对挡土墙的地震反应及其抗震设计至关重要。鉴于此,采用Pasternak地基模型,建立了地震作用下层状地基中挡土墙的动力位移控制方程,通过引入修正Vlasov地基模型中的迭代算法,推导了层状地基弹簧系数和剪切系数的表达式。通过本文方法计算结果与已有方法计算结果的对比分析,充分证明了本文方法的正确性和可行性。同时,通过设计不同的挡土墙后软夹层厚度、埋深和土层模量比,进一步明确了软夹层的不同存在条件对挡土墙地震反应的影响规律。
Dynamic interaction mechanism between soil and retaining wall is very important for the seismic design of retaining wall. However, most of the present analysis methods for the dynamic interaction of soil-retaining walls under earthquake action focused on homogeneous soil and ignored the influence of layered soil characteristics. Pasternak’s foundation model can accurately consider the interaction between soil and underground structure under earthquake action and can calculate the influence of layer soil. In this study, on the basis of the displacement governing equation of retaining walls in multilayered soils in Pasternak’s model, the exact expressions of spring and shear coefficients are obtained by introducing the iterative method in the modified Vlasov’s model. Compared with the existing analytical method, the accuracy of the proposed methods is proven. A parametric study is performed to investigate the seismic response of the retaining wall under different interlayer soft soil conditions, including thickness, depth and hardness of the interlayer soft soil behind the retaining wall.
