显式拉格朗日差分法在链子崖危岩体锚固工程中的应用

Explicit Lagrangian Difference to the Stabilization of the Lianzi Cliff Dangerous Rock Mass

显式拉格朗日差分法是相对于隐式差分法的一种新型数值分析方法。简要介绍了这种方法的基本原理，并将基于该方法开发的ＦＬＡＣ程序应用于链子崖危岩体的锚固工程中，对锚固前后危岩体的状态进行了对比。最后总结了使用ＦＬＡＣ程序的一些经验和体会。

The explicit Lagrangian method is a new numerical analytical method different from the implicit difference method. The basic principle of the method is briefly described. The FLAC software developed on the basis of the method was used in the anchoring project of Lianzi Cliff dangerous rock mass for comparison of the conditions of the hazard cliff before and after the treatment. It is concluded with the summation of the experience gained from the use of the FLAC software.
