摘要
探讨了东涌水库输水隧洞钻爆施工方案的难点,包括如何根据围岩类型选择钻爆方法和爆破参数、控制爆破方向和装药量以减少对围岩的震动和破坏、处理隧洞进出口与边坡衔接处的安全问题,以及在不良地质洞段施工应遵循的原则.针对这些问题,提出了一系列相应的解决方案和优化策略,以确保施工过程的安全性和稳定性,同时提升施工效率和质量.
Abstract
This article explores the difficulties of drilling and blasting construction plans for the water conveyance tunnel of Dongyong Reservoir.It includes how to choose drilling and blasting methods and parameters based on the type of surrounding rock,control the blasting direction and charge to reduce vibration and damage to the surrounding rock,handle safety issues at the junction of tunnel entrances and exits and slopes,and follow principles for construction in unfavorable geological tunnel sections.A series of corresponding solutions and optimization strategies have been proposed to address these issues,in order to ensure the safety and stability of the construction process,while improving construction efficiency and quality.
