University ,Changsha 410075,HunanAbstract: In view of the deficiency in methods for choosing zonation indicators of mudflow danger degrees,a new method for choosing zonation indicators of mudflow danger degrees is put forward based on the rough set theory in this paper.Firstly,according to the environmental conditions of forming mudflows,an indicator choice system is established.Then the indicators for choice are discretized by indicator grading.Finally,based on the discernable matrix of the rough set,a core set of the indicators is found and the representative indicators are sieved out.

摘 要：针对现有泥石流危险度区划指标选取方法的不足，本文基于粗糙集原理，提出了一种新的区划指标选取方法，即首先根据泥石流形成的环境背景条件，建立备选指标体系，然后根据指标等级对备选指标离散化处理，最后利用粗糙集的分辨矩阵对指标进行求核约简，筛选出代表性指标。

The detailed algorithm on analyzing cracks exploration inside blocks is: enriched approximations which describe singular crack tips fields and discontinuous crack faces are employed under the Partition of Unity theory; the enriched nodes surrounding crack tips or faces are respectively mapped with corresponding enriched degrees of freedom, and the solution of all these degrees of freedom is uniformly proceeded by the implicit iteration algorithm of DDA, then fracture and breakage of DDA blocks can be analyzed. The numeric examples show this algorithm is rational and efficient.
