荷载试验结果表明,板中和板边受荷时弹性半无限地基板的有限元解(位移法),同实测的挠度曲线和应变曲线相吻合,而板角受荷时则Winkler地基板的有限元解符合实测挠度曲线和应变曲线。水泥混凝土路面下地基回弹模量的取值,在板中受荷时要比承载板实测结果提高2～3倍。
The load test results show that the finite element solution (displacement method) of the elastic semi-infinite substrate in the middle of the slab and the edge of the slab are consistent with the measured deflection curve and strain curve, while the finite thickness of the Winkler substrate is limited when the slab angle is loaded. The meta solution meets the measured deflection curve and strain curve. The value of the resilient modulus of the foundation under the cement concrete pavement is increased by 2 to 3 times than that of the bearing plate when loaded in the slab.
