摘要
依托某山区机场斜坡基底高填方边坡支护工程,运用midas-GTS有限元程序建立数值计算模型,对整体边坡稳定性、差异沉降、支护设计方法等进行研究分析。结果表明:通过优化边坡坡率、增设锚索抗滑桩和提高填筑体施工质量等方法,有效提高边坡整体稳定性,后期监测数据显示边坡整体稳定性良好。
Taking an engineering of high filling slope on slope base in the mountainous airport as an example,the overall stability,differential settlement,support design method of the slope are studied and analyzed by midas-GTS finite element model.The results show that the slope overall stability is improved effectively by optimizing slope rate,setting anchored slide-resistant pile and increasing the construction quality of filling body.Later monitoring data shows that the slope overall stability is in good condition.
