摘　　要：结合西南地区机场工程实践,研究了红层结构特征、垂向分布特点与工程特性;分析了机场工程中红层土石比确定的现状;提出施工土石比、设计土石比概念和适宜红层土石比的勘探手段、计算方法,以及勘察初步确定土石比,试验段校核土石比,施工调整土石比的程序,在西南某机场中运用效果良好。Combining with the engineering practice of airport projects in southwest China, this paper studied the structural characteristics, the vertical distribution and the engineering properties of the red bed, and analyzed the determination of the soil-rock ratio thereof, and then proposed the followings ： the concepts of the soil-rock ratios for construction and in design, both exploration means and calculation method suitable for the soil-rock ratio of the red bed, and the procedures to decide soil-rock ratio by exploration, to verify the ratio of the test section, and to adjust the ratio during construction, which are applied with good effect in a airport in the southwest.
