暗结构汽车荷载扩散计算分析

摘要

暗板桥、涵洞等暗结构在公路设计中占有很大比例,其受力分析对暗结构的安全至关重要。通过对车辆活载在板顶填土的影响下产生的扩散效应的探讨,提出了关于新规范中车辆荷载扩散效应的一些看法。%Hidden structures like slab bridge and culvert take up a large proportion in highway design, force analysis of which is very important for the safety of hidden generated by vehicle live load with the influence of roof slab load in new specifications are proposed. structure. Through the discussion on spreading effect filling , some opinions about spreading effect of vehicle
