浅析高速公路改扩建工程中路基拼接设计

Shallow highway reconstruction of roadbed design stitching

路基拼接设计是高速公路改扩建工程中的重点和难点之一。路基拼接设计的核心是减少新旧路基之间的差异沉降,消除由于差异沉降而引起的道路纵向裂缝和横向不均匀沉降。本文通过理论分析和对现有工程的调查,对路基拼接设计的特殊性、有限元分析、病害类型、处治方案等进行了系统的论述,提出了高速公路改扩建工程中路基拼接设计的一般设计方法。

Mosaic is the highway roadbed design projects of the key and difficult. Mosaic is the core of roadbed design and reduce the difference between roadbed subsidence, eliminate the differences and settlement of lateral and longitu- dinal cracks road uneven settlement. Based on the theoretical analysis and engineering survey, existing particularity of subgrade stitching designs, finite element analysis, disease types, treatment plan, the system, proposes the highway subgrade projects in the general design stitching design method.
