摘要
采用弹性层状体系的力学模型,利用有限元法对由于地基不均匀沉降引起的路面附加应力进行计算和分析,得到过路构造物台背处差异沉降对路面受力状态影响的主要因素,并对台背处差异沉降的允许范围进行了探讨。
The mechanics form of the elasticity storeylike system and the logarithm of timw fitting method logt of limited dollar are adopted to calculate and analyze the roadbed additional stress caused by the differerent sinks of the road foundation ,to get the influence of the roadbed stress situation caused by the differerent sinks of the pedestal back of the construction things over the road,and to study the permission range of the different sinks of the pedestal back.
