摘要
顺层滑坡问题在我国西部工程建设中较为突出和普遍。利用有限元法,针对沪蓉西高速公路深切顺层岩质边坡问题,对抗滑桩支护前后边坡的应力场、位移场及稳定性进行模拟分析。对结果的分析比较表明:抗滑桩支护结构可有效地抑制顺层边坡的变形和滑动,明显提高边坡的整体稳定系数,对维护顺层边坡的整体稳定性具有良好的效果。
Consequent landslide is much protrusive and general in the engineering construction in the west of China. Aiming at the problem of deep-cut bedding rock slope in the west of Shanghai-Chengdu national road, the stress field, displacement field and stability of the slope before and after supported with anti-slide piles are simulated and analyzed by means of finite element method （FEM）. The analysis and comparison show that anti-slide pile supporting structure can control effectively the displacement and slide of the bedding slope, and increase apparently its entire stability coefficient, then has favorable effect to maintain the entire stability of the bedding slope.
