摘要
蚌淮高速公路路基填筑量较大,沿线土地资源珍贵,存在取土困难的问题;同时项目区的淮南煤矿为特大煤矿,矸石山已成为煤矿发展的一大负担,未能得到充分利用。结合蚌淮高速公路第6标段K37+340^+490试验段施工,通过室内及现场试验,研究确定煤矸石填筑路基的适用性、施工工艺及质量控制标准,从而指导工程施工。
The filling amount of subgrade along Bengbu-Huainan Highway is large, but the land resource along the line is rare, which causes difficulty in soil borrowing. At the same time, in the Huainan Coal Mine, a grand mine in the project area, the gangue dump has become a big burden and not been fully utilized yet. Combining with the construction in the trail section of the Section 6 K37 ＋ 340 ～ ＋ 490 of Bengbu-Huainan Highway, the applicability, construction technology and quality control standard for subgrade filled by coal gangue were studied and then determined by indoor and field tests, which could guide the engineering construction.
