文章依托某高速公路路基改造工程,采用大型有限元计算软件MARC对单侧加宽和双侧加宽模式下的新旧路基变形性状进行计算分析,其结果显示双侧加宽模式较单侧加宽模式更具优势,为后续类似旧路拓宽工程的设计和施工提供了理论依据。
The article relies on a highway subgrade reconstruction project, the use of large-scale finite element software MARC calculation of unilateral widening and bilateral widening mode of deformation of old and new subgrade calculation results show that bilateral widening mode wider than the unilateral The model has more advantages and provides a theoretical basis for the follow-up design and construction of similar old road widening projects.
