无网格方法特别适用于模拟岩体中的节理等不连续面问题。无网格谢泼德最小二乘法（MSLS）是近年来发展起来的一种新的无网格方法，它克服了其他无网格方法的一些局限性。本文将MSLS方法推广到节理岩体的模拟，将节理模拟为控制近场应力的不连续面。应用该方法对锦屏水电站坝肩岩质高边坡进行了分析。根据沿着潜在滑动面的应力计算结果，计算了边坡的安全系数，并与常规条分法进行了比较。结果表明，MSLS方法在岩质边坡稳定性分析中的可行性，也揭示了一些有趣的区别于传统的条分法。最后，对本研究的一些发现和尚待解决的问题进行了讨论，这些问题可以作为未来发展的主题。
The meshless methods are particularly suitable for modeling problems with discontinuities such as joints in rock mass. The meshless Shepard and least squares (MSLS) method is a newly developed meshless method, which overcomes some limitations with other meshless methods. In the present paper, the MSLS method is extended for modeling jointed rock mass and the joint is modeled as discontinuity governing the near-field stress. A substantial high rock slope by the dam shoulder of Jinping Hydropower Station is analyzed by the developed method. Safety factors are evaluated based on the stress results along potential slip surfaces and compared with the conventional slice methods. The results demonstrate the feasibility of using the MSLS method in rock slope stability analysis and also reveal some interesting differences from the conventional slice methods. Some findings and outstanding issues demonstrated in this study are discussed in the end, which can be the topics for future development.
