摘要
针对最大填筑高度40 m的重庆黔江舟白机场大粒径土石混填料高填方,采用强夯法对高填方地基及填筑体进行填筑处理,通过不同的虚铺厚度的现场强夯试验,从而获得强夯工艺和参数,填料的颗粒级配得到极大改善,提高施工效率,降低了工程投资。
Aiming at large particle dust and rock mix filling high fill of Qianjiang Zhoubai airport in Chongqing with 40 m highest filling height,the high fill foundation and fill body were treated using dynamic consolidation.By field dynamic consolidation tests with different virtual paving depth,the dynamic consolidation technology and parameters were gained,the grain composition of filling was improved greatly,which improve the construction efficiency and reduce the engineering cost.
