公路路基改建的施工程序及要求

Construction procedures and requirements of highway subgrade reconstruction

公路工程中的路基施工十分重要,它是根据地面路线的纵坡要求进行开挖,或将路基的平面位置堆填成石质结构物。路基作为公路的基础,除了需承受各种交通工具的载压之外,还需经受外界因素对其造成的影响,因此对路基进行施工时必须结合施工场地的实际地形和地质,并认真分析施工区域的地理条件,采取可行的施工方案使施工质量得到有效保障。

Subgrade construction is very important in highway engineering, which is excavated of road surface requirements of longitudinal slope, or filled by stone structure in roadbed. As the basis of highway roadbed, in addition to the load pressure caused by traffic, subgrade is also affected by the external factors. Therefore, the con- struction of subgrade should be combined with site of the actual terrain and geology, and carefully analyses regional geographical conditions to guarantee construction quality by adopting feasible construction scheme.
