摘要
西南地区某机场高填方、场区地质条件复杂、分布有软弱土层,因而高填方体地基的稳定性问题是关键的工程技术问题。以场区西1#沟为例,在地质岩体力学环境条件分析研究的基础上使用先进的FLAC-3D数值模拟技术对高填方体地基的失稳模式进行分析,在此基础上结合二维平衡计算对高填方体的稳定性进行评价,并对地基工程处理措施提出相应的建议。
High embankment, complex geological conditions accompanied with soft soil are the main characteristics for an airport in southwest China. The stability of the high embankment foundation is a key engineering technology problem. This paper uses the advanced FLAC -3 D numerical simulation analysis technology to analyse the unstability mode of high embankment foundation on the base of analysis and research on the geology - rock mechanics conditions taking west No. 1 slope as an example. On these bases this paper adopted two - dimensional limiting equilibrium method to evaluate the stability of the high embankment. At last,the optimization suggestion on the engineering disposal measure to the site foundation is brought forward.
