摘 要: | 以四川各地红层泥岩为依托,采用灰色聚类法对红层泥岩填料进行分级评判,研究西南红层泥岩作为高速铁路路基填料的适用性。结果表明:四川大部分红层泥岩属于优质填料;四川盆中区红层泥岩属于T3级填料,无法作为高速铁路路基填料使用,需进行换填;遂渝及达成铁路的红层泥岩填料均达到了T1级,可作为路基填料直接使用。

Study on the Discrimination and Application of the Southwest Red Mudstone Filler Based on the Grey Clustering Method |
| |
Abstract: | Based on the red mudstone in all parts of Sichuan, the red mudstone filler is graded and evaluated by grey clustering method and the suitability of the red mudstone as the subgrade filler of high-speed railway is studied. The results of research show that most of the red mudstones in Sichuan are of high quality, and the red mudstones in Sichuan basin are of grade T3, which cannot be used as subgrade filler in high-speed railway and need to be replaced. The red mudstone fillers of Suining—Chongqing Railway and Dazhou—Chengdu Railway have reached Grade T1 and can be used as subgrade filler directly. |
