摘　　要：各类工程建设都会涉及土石方工程,确定土壤和岩石的分类对其工程造价影响较大。从岩石坚固性系数出发,剖析现行电力工程概(预)算定额岩石(普氏)分类的缺陷,并通过对岩石开挖难易程度影响因素的分析,提出以岩体基本质量指标BQ值为基础的分类方案。All kinds of construction will involve earthwork,how to determine the classification of soil and rock engineering cost.Based on the rock firmness coefficient,this paper analyzes the defects of rock(Proctor)classification in the current estimate and budget quota of power engineering,and puts forward a classification scheme based on the basic quality index BQ value of rock mass through the analysis of the influencing factors of rock excavation difficulty.
