固体力学的物质点方法（MPM）是由Sulsky及其同事在20世纪90年代首次提出的。从那时起，它一直在发展越来越多的追随者，尤其是因为它能够轻松处理大变形问题。这一特征最近引起了岩土工程研究人员的注意，他们有很多涉及大变形的问题需要解决。然而，从最近的出版物中可以清楚地看到，许多岩土工程研究人员发现在许多领域使用MPM存在困难。在本文中，我们访问这些问题的三个领域，并强调我们已经开发的解决方案。我们希望这可以消除一些障碍的使用和进一步发展的MPM的岩土工程问题在未来。
: The Material Point Method (MPM) for solid mechanics was first proposed by Sulsky and co-workers in the 1990s. Since then it has been developing a growing band of followers not least because of its ability to handle large deformation problems with ease. This feature has more recently come to the notice of geotechnical researchers who have plenty of problems to solve involving large deformations. It is clear from recent publications, however, that many geotechnical researchers have found difficulties with the use of the MPM in a number of areas. In this paper we visit three of these problem areas and highlight solutions we have developed. It is to be hoped that this can remove some of the roadblocks to the use and further development of the MPM for geotechnical problems in future.
