为了确保由于修建高速公路阻断原水系、道路在高速公路完成后能恢复正常功能,高速公路在设计时通常采用桥涵、通道来达到目的,随着国家西部大开发战略的步步深入,高速公路已经逐步深入到了中国的中南西南乃至西部山区、高原,为了满足高填的受力要求,拱形通涵的应用已经是日趋频繁,现对拱形通涵的施工技术进行简单的探讨。
In order to ensure that the original highway system is blocked after the expressway is built and the normal function of the road can be restored after the completion of the expressway, the expressway is usually designed with bridges, culverts and tunnels as the design progresses. With the further development of the national western development strategy, It has been gradually penetrating into the mountainous and plateau areas in south, southwest and even west China in China. In order to meet the requirements of high fill, the application of arched culverts has become more and more frequent. The construction technology of arched culverts is briefly discussed.
