摘要文中建立了工程中常用的人字式铺砌的联锁块铺面的三维有限元模型,比较了三维模型与平面应变模型和轴对称模型的区别以及不同铺砌方式对联锁块铺面性能的影响。按联锁块铺面结构的主要破坏形式和结构响应,将具有众多缝隙的联锁块层等效为一均质弹性层,总结了联锁块间有初压应力条件下的联锁块层等效模量的变化规律,给出了联锁块层等效模量与接缝宽度、初压应力系数和接缝填料模量比的回归关系式,并给出了常见条件下的联锁块层等效模量值。 A three-dimensional finite element model of the herringbone-style paving interlocking block pavement,which is more commonly used,is established.The impact of the difference between this model and plane strain model,axisymmetric model of interlocking block pavement and different paving way are compared.Based on its destroy forms and structural response,the block layer is equivalent to a simple homogeneous elastic layer.And the regular patterns of the interlocking block layer equivalent modulus with initial compressive stress are summarized.The regression formula of the interlocking block layer equivalent modulus with the gap width,initial compressive stress coefficient and gap filler modulus ratio is established and the recommended interlocking block layer equivalent modulus values are given in the common conditions.
