公路高填土涵洞的加固设计

Reinforcement Design of Highway High Fill Soil Culvert

随着我国公路路网建设规模的不断扩大,工程区域的地质地形条件越来越复杂,给公路工程的设计施工增加了很大的难度。特别是在山区等地理环境下进行高等级公路涵洞建设时,需要采用高填土的设计方法。由于高填土涵洞比较特殊,容易出现裂缝,影响涵洞结构的稳定性,因此,需要对裂缝的成因进行全面的分析,并采取相应的加固设计方法。

With the continuous expansion of the construction scale of highway network in China,the geological and topographic conditions in the engineering area become more and more complex,which makes the design and construction of highway engineering more difficult.Especially in the construction of culverts of high-grade highway in mountainous areas and other geographical environments,it is necessary to adopt the design method of high fill.Because the high fill culvert is special,it is easy to crack,which affects the stability of culvert structure Therefore,itis necessary to analyze the causes of cracks comprehensively and adopt corresponding reinforcement design methods.
