摘要
以某高陡边坡道路为研究对象,根据地质地形条件提出了道路扩建及相应的支挡方案,并利用有限元软件模拟分析了 h型双排桩在路基支挡中的应用效果.分析结果表明:路面最大沉降为20 mm,桩顶最大水平位移为12.7 mm,前排桩和后排桩最大弯矩分别为470 kN·m和1 808 kN·m,路基边坡的安全稳定性系数为1.5,满足规范设计要求.
Abstract
Focusing on a high and steep slope road,this paper proposed a road expansion scheme and corresponding retaining scheme according to the geological and topographic conditions and simulated the application effect of the h-type double-row pile in the subgrade retaining by finite element software.The analysis results showed that the maximum road settlement was 20 mm,the maximum horizontal displacement of the pile top was 12.7 mm,the maximum bending moment of the front and rear piles were 470 kN·m and 1 808 kN·m respectively,and the safety stability coefficient of the subgrade slope was 1.5,which all met the specification requirements.
