滑坡问题是危害非常大的自然灾害之一,滑坡的产生会阻碍交通、淤堵河道和毁坏村庄,对人民生活造成极大的危害,同时也会造成巨大的经济损失。工程中计算边坡问题应用最多的一种方法就是极限平衡法,尤其是极限平衡法中的条分法,但该方法在处理复杂边界条件、影响因素较多时存在较多困难难以应用。而有限单元法恰巧在这些方面具有很大的优势,随着计算机技术以及有限元理论的的发展,有限单元法势必成为边坡工程计算的重要方法。基于ANSYS软件的有限单元法分析边坡问题具有计算效率高,成本低,计算精度高等优势,所以有限单元法关于边坡问题的计算理论仍是目前研究的一个重要问题,随着计算理论的不断完善,有限单元法将是今后边坡工程计算的一个重要发展方向。
Landslide is one of the most dangerous natural disasters. Landslides can hinder traffic, silting up rivers and destroying villages, causing great harm to people’s lives and causing huge economic losses. One of the most widely used methods for calculating slope problems in engineering is the limit equilibrium method, especially the striping method in the limit equilibrium method. However, this method has more difficulties and difficulties in dealing with complex boundary conditions and more influencing factors. The finite element method happens to have great advantages in these aspects. With the development of computer technology and finite element theory, the finite element method is bound to become an important method of slope engineering calculation. Finite element method based on ANSYS software can effectively analyze slopes and has the advantages of high computational efficiency, low cost and high accuracy. Therefore, the calculation theory of finite element method is still an important issue in current research. With the continuous development of computational theory The perfect and finite element method will be an important development direction of slope engineering calculation in the future.
