基于Abaqus有限元模拟的反h抗滑桩对陡坡路基沉降的影响研究

Research on the Influence of Anti-h Anti-slide Piles on the Settlement of Steep Slope Roadbed based on Abaqus Finite Element Simulation

通过使用abaqus有限元模拟软件模拟冀西北地区的陡坡路基,并计算分析在桩间间距、h桩前后桩距以及陡坡坡度变化的情况下陡坡路基的沉降变形情况,研究表明:随着桩间距的增大,陡坡路基边坡的最大变形量也不断扩大,当桩间距为8 m时,变形量达到峰值,且为22.94 mm;随着前后桩距的增大,陡坡路基的最大变形量先到达一个峰值,当过了峰值之后,随着前后桩距的增大,陡坡路基的最大变形量随之降低;当改变陡坡坡度时,随着陡坡的增大,陡坡路基沉降量也随之增大,当陡坡坡度达到36.158 m时,变形量最大。

In this paper,abaqus finite element simulation software is used to simulate the steep slope roadbed in northwestern Hebei,and the finite element software is used to calculate the simulation ability to analyze the settlement and deformation of the steep slope roadbed under the conditions of changes in the spacing between piles,the distance between piles before and after the h,and the slope of the steep slope.It shows that with the increase of the pile spacing,the maximum deformation of the steep slope subgrade slope also continues to expand.When the pile spacing is 8m,the deformation reaches a peak value of 22.94mm;with the increase of the front and rear pile spacing,the steep slope subgrade.The maximum deformation reaches a peak first.After the peak,as the distance between the front and rear piles increases,the maximum deformation of the steep slope subgrade decreases;when the steep slope increases,the steep slope subgrade settles.The amount also increases.When the steep slope reaches 36.158m,the amount of deformation is the largest.
