摘要
基于GM-4勘探井井场填方边坡的基本特征,调查研究了边坡在钻井周期发生的变形破坏特征,并采用极限平衡法进行了计算、模拟和对比分析,掌握了填方边坡随坡度变化而呈现的稳定性变化特征,分析结果与填方边坡宏观变形现象均具有较高的吻合度。
Based on the basis characteristics of GM-4 exploration site embankment slope,this paper investigated and researched the deformation and failure characteristics of slope in drilling well cycle,and made calculation,simulation and comparison analysis using limit equilibrium method,mastered the stability change characteristics of embankment slope with slope change,the analysis results and embankment slope macroscopic deformation phenomena both had good agreement.
