摘要:: 以贵州六盘水月照机场东北端边坡为例,采用FLAC3D软件对不同填筑层数下机场高边坡填筑竣工期填筑体沉降进行了模拟,系统分析填筑层数对平均填筑高度达63 m的高填方边坡沉降的影响。结果表明,当模拟层数

Abstract:: Taking the shuiyuezhao airport on the northeast liupanshui slope for example. The aim of this paper is using the software of FLAC3D to simulate the settlement of the filling body of high filled slope of airport during the completion period under different filling layer numbers to analysis the influence of simulated filling layer number on settlement of high slope filling body systematically, and the filling height of which is up to 63 m. The results show that the biggest settlements fluctuate up and down with the increase of simulated filling layer number, and Contour of z-displacement presents discontinuity between layers when the numbers of simulated filling layer less than equal to 7, and the biggest settlements tends to a stable value and do small fluctuations around it when the simulated filling layer number continue to increase; also contour of z-displacement tends smooth and continuous gradually. The biggest settlements tend to a stable value when the numbers of simulated filling layer more than equal to 7, which’s calculation precision of the settlement satisfies the project need. For the high filled slope which’s average height is 63m, 7~9 simulated filling layer number was best recommended.
