针对四川省攀枝花机场高填方土石混合料填筑体工程 ,分别采用 2 0 0 0kN·m和 3 0 0 0kN·m夯击能、 3 5× 3 5m正方形布置夯点对松铺厚度为 4m、 5m、 6m土石混合填筑料进行现场单点夯试验 ,获得了不同夯击能和不同松铺厚度时单点夯沉量、夯沉体积与夯击次数的关系 ,并对夯后填筑体密实度和变形模量进行了现场测试与评价 ,在此基础上 ,最后提出了采用 2 0 0 0kN·m夯击能、松铺厚度为 4m ;3 0 0 0kN·m夯击能、松铺厚度为 5m和 6m的土石混填料强夯施工参数及控制标准 ,以指导山区机场高填方填筑体施工。
According to the project of high-fill soil-rock mixture filling body of Panzhihua Airport in Sichuan Province, the impact energies of 2000 kN · m and 3000 kN · m were respectively adopted, and the thickness of 3.55 m 3 , 5m, 6m earth and rock mixed filling material on-site single-point ram test to obtain the impact of different tamping thickness and thickness of single-point rammer, rammer volume and the number of times of impact, Body compactness and deformation modulus were tested and evaluated on site. On the basis of this, the paper put forward that the use of 2 0 0 kN · m tamping energy, the thickness of 3 t, 3 000 kN · m tampon energy, Depth of 5m and 6m thickness of the earth and rock mixed material dynamic compaction construction parameters and control standards to guide the airport airport high fill filling body construction.
