露天采矿台阶楔形体稳定性(Bench Wedge Stability)
1 引言
露天采矿台阶的破坏形式主要有三种: 平面破坏, 楔形破坏和岩石坠落. 其中楔形破坏是最常见的破坏形式，如下图所示。本文使用机器学习方法在GeotechSet数据集内调查了这个方向最相关的研究工作。

2 调查方法
如果使用C(n,3)的组合查询方法，那么对"bench wedge failure stability"将会得出大量的相关文档，由于我们的着重点在"bench", 因此分开运行能够缩小范围，得到更精确的解答，然后根据搜索的数据映射出文档的名称。运行结果如下：
(I) bench wedge stability
这个搜索得到6个文档：
(1) Feasibility Pit Slope Design
(2) Kinematic assessment of composite failure mechanisms in pit slopes
(3) Site investigation and geological data collection
(4) chuquicamata
(5) Bench Scale Stability Analysis
(6) Geotechnical Review of LOM Cariboo Pit and Springer Pit Slope Designs
(2) bench wedge failure
这个搜索得到8个文档：
(1) Assessing slope performance
(2) Characterisation of High Rock Slopes using an Integrated Numerical Modelling
(3) Kinematic assessment of composite failure mechanisms in pit slopes- a novel slip surface identification algorithm for DFN models
(4) Monitoring and managing large deformation pit slope instabilities at a British Columbia copper mine
(5) Site investigation and geological data collection
(6) Slope Stability Analysis and Design Based On Probability Techniques at Cassiar Mine
(7) Geotechnical Review of LOM Cariboo Pit and Springer Pit Slope Designs
(8) rock wedge failure
可以看出，其中一部分文档在两个搜索结果中都有，这显示出这些文档是最相关的研究工作。
[1] Kinematic assessment of composite failure mechanisms in pit slopes- a novel slip surface identification algorithm for DFN models
[2] Site investigation and geological data collection
[3] Geotechnical Review of LOM Cariboo Pit and Springer Pit Slope Designs
3 文档的相似度
Paraphrase Mining是在一个句子集合中寻找彼此之间最相似的方法，这个算法最初用来查找硬盘内的相似文档，利用这个方法可以得出上述两个搜索结果中最相似的文档，按照相似度排列，其前10个结果如下：
