摘　　要：地应力钻孔是钻探技术在地应力测量与监测科研领域新的应用,具有特殊的质量控制要求,也缺乏规范的质量评价标准,分析研究探讨其质量评价方法和标准对控制钻孔质量具有一定意义。本文通过对大量应力钻孔项目实践经验的分析和总结,在充分研究该类型钻孔属性与特性的基础上,从应力孔质量控制要素分析入手,寻找应力孔质量评价的相关因子,并对普通地质钻孔质量控制要素适用性进行分析论证。通过对评价因子的权重分析,探讨并提出了应力钻孔成果质量评价方法和评价标准,方法独特新颖。特别是独特的质量要素分类方法,借鉴建设工程的质量评价方法和分析研究推荐的评价标准,具有合理的逻辑性和较好的操作性,对该类型钻孔成果质量评价具有现实的指导意义,也可为研究和制定类似的钻探项目成果质量评定规范性标准,提供借鉴和参考。Geo-stress drilling is a new application technique for drilling technique used to measure and monitor the geo-stress, which has special quality control requirements; however, there are not enough normal quality evaluation standards. Hence it is very import significance to analyze and research its quality evaluation methods and standards.Based on the analysis and summarization of the practical experience from a large number of geo-stress drilling projects, this paper studies the quality control elements of the geo-stress hole on the basis of fully studying the drilling properties and characteristics, and finds the relevant factors of the stress hole quality evaluation, and states the applicability for the common geological drilling quality control elements. Through the analysis of the weight of the evaluation factors, the quality evaluation methods and evaluation criteria of stress drilling results are discussed and put forward, and the method is unique and novel. Especially the unique quality factor classification method,based on the quality evaluation method of construction project and the recommended evaluation standard, has reasonable logic and good operability, and it has practical significance and reference for the quality evaluation of the drilling results.
