摘　　要：滇西地区地层间软弱破碎带的物质组成、水理特性、工程特性千差万别,规律性差。为确保安全施工,进一步综合分析地质资料,预测可能出现的工程地质问题,针对不同特性围岩采取针对性措施,以保证隧道施工安全,确保工程顺利施工。The material composition, water properties and engineering characteristics of the weak fractured zone in western Yunnan are different from each other, and the regularity is poor. To ensure safe construction, more comprehensive analysis of geological data is carried out to predict the engineering geological problems that may develop. According to different char- acteristics of the surrounding rock, specific measures are taken to ensure the safety and smooth construction of the project.
