有限元法的特点及其在边坡工程中的应用实例

Characteristic of finite element method and its application example in slope engineering

简述了在岩土工程中常用的有限元位移法的特点及计算步骤,对边坡分别在天然状态和坡顶均布荷载状态下的应力、应变作数值分析比较,分析结果显示在有荷载作用条件下边坡的塑性区贯通性强,相比天然状态下更易发生失稳破坏。

The article summarized the characteristics and compute procedure of finite dement method frequently used in geotechnical engineering, conducted numeric analysis and comparison of the stress and strain in nature and in deformation condition of top slope. The analysis consequence demonstrated the slope had more pierce capability in plastic area in the load condition, and it is easier to be destabilized and destructed than in nature.
