高速公路既有路堤受桥梁施工影响的分析

借助有限元分析软件，以某铁路桥梁跨越高速公路的施工过程为背景，建立三维有限元模型探讨其施工过程对临近高速公路路堤的影响及该桥梁的自身沉降。通过研究，取得了桥梁施工过程对高速公路路堤影响形式，以及桥梁在整个施工过程沉降与工后沉降的进一步认识，对于桥梁施工时保护临近建筑设施有一定的参考意义。

Analysis on the influence of highway existing embankment to bridge construction

Using the finite element analysis software, taking the construction process of a railway bridge across highway as the background, estab- lishment of three-dimensional finite element model, discussed the influence of construction process to near the highway embankment and itself set- tlement of bridge, through the research, obtained the influence form of bridge construction process to highway embankment, and further under- stood the entire process settlement of bridge and settlement after construction, had certain reference significance for protection of near the building facilities in bridge construction .
