摘要
在工程施工中,斜井施工具有体型控制难度大、开挖出渣运输困难、支护难、安全隐患大的特点,往往制约着整个工程的进度。结合马来西亚胡鲁项目应急-电缆-通风隧洞工程实际,对小断面、大坡度隧洞顺坡开挖、支护及安全保障等方面进行了研究,解决了在隧洞爆破、出渣及支护等方面遇到的技术难题,可为类似工程提供借鉴。
In hydropower project construction,inclined shaft construction is characterized with shape control difficulties,excavation muck transport difficulties,supporting difficulties and potential safety hazards. With engineering practice of emergency-cable-ventilation tunnel in HU LU project in Malaysia,top-down excavation,support and security insurance for small section and steep slope tunnel are discussed. Technical problems in tunnel blasting,mucking and supporting are solved. The experiences will provide references to the similar projects.
