泥石流预报中地质判据的主要因素分析

PRIMARY FACTOR ANALYSIS OF GEOLOGIC CRITERIA IN THE PREDICTION OF DEBRIS FLOW

本文在大量实际工作和资料积累的基础上,就泥石流预报中地质判据的主要因素进行分析。采用岩组类型、地质构造特征、岩体破碎程度、岩体风化程度和固体物质补给方式等五项因素作为评价泥石流地质条件的基本变量,并提出地质判据中主要因素的分类标准和实例。

Based on a large amount of practical tasks and dataaccumulated, the primary factors of geologic criteria in the prediction ofdebris flow have been analysed in this paper. The rock types, geologicstructural characteristics, rock breaking degree, rock weathering extent andthe providing way of solid materials are taken as the 5 basic variables toevaluate geologic conditions of debris flow gullies, and the classifica-tion standard and example of primary factors in geologic criteria arealso presented in the meantime.
