室内模型板试验表明,双层混凝土板有限元解的埋论挠度曲线和应变曲线同实测值相吻合。双层混凝土板下的地基弹性模量随双层板的抗弯刚度而变化,结合式双层混凝土板下的地基模量是承载板在地基表面测得模量值的4～6倍,而分离式双层混凝土板则为2～3倍。层间设置隔离层的双层混凝土路面可近似地按分离式双层板计算,其余的双层混凝土路面可按结合式双层板进行计算。
The indoor model test shows that the deflection curve and the strain curve of the finite element solution of double-layer concrete slab agree well with the measured values. The elastic modulus of foundation under double-decked slab changes with the flexural rigidity of double-deck slab. The modulus of foundation under combined double-deck slab is 4 ~ 6 times the modulus of slab measured on the surface of foundation Split double concrete slab is 2 to 3 times. The double-decker concrete pavements with interlayers of decks can be approximated by separate double-decks and the remaining double-decker pavements can be calculated as double decks.
