刘江至西南绕城段改扩建工程地基处理计算方法研究

Foundation Disposal Calculation Method of Liujiang to Southwest Ring Road Section Reconstruction and Extension

根据河南省连霍高速公路刘江至西南绕城段改扩建工程施工图设计经验,对其改扩建过程中双侧加宽路段的地基沉降控制标准及计算方法的选择加以介绍,同时结合工程实际,选取典型断面分别用有限单元法和分层总和法进行计算,其结果表明二者具有良好的相关性,这可用于简化工程计算,且为其他类似工程提供参考。

According to the construction documents design of Liujiang to Southwest ring road section of Henan province Lianyungang-Hoerkwosze expressway, the paper introduces the foundation settlement control standard and calculation method of two-side widened section during reconstruction and extension, at the same time, selects typical cross-section to do the calculation through the finite element method and layerwise summation method integrating with the project. The results indicate that the two methods are closely related. It can be used in simplifing the engineering calculations and serve as guidance for similar engineering.
