本文根据弹性理论和粘弹性理论之间的对应法则,推导了粘弹性地基上板在静荷载作用下的挠度计算公式。为使路面计算荷载模型较好地反映实际情况,本文在上述基础上又推导了粘弹性地基上板在移动荷载作用下的挠度计算公式。该公式为今后刚性路面设计由动荷载代替静荷载、粘弹性地基代替弹性地基提供了理论依据。
Based on the corresponding laws between elasticity theory and viscoelasticity theory, this paper deduces the formula for calculating the deflection of the slab on the viscoelastic foundation under static load. In order to make the road load calculation model reflect the actual situation better, this paper also deduced the calculation formula of the deflection of the upper plate of the viscoelastic foundation under the action of moving load. This formula provides a theoretical basis for future design of rigid pavements by using dynamic loads instead of static loads and viscoelastic foundations instead of elastic foundations.
