城市复杂环境下水工隧洞静态爆破施工技术

Static Blasting Construction Method for Hydraulic Tunnel Under Urban Complex Environment

静态爆破技术是一种对岩石进行破碎和切割的新技术,与传统的爆破技术相比,具有无振动、无噪声、无飞石等特点,应用范围十分广泛。论文结合广州市南沙区凤凰湖隧洞工程,介绍了静态爆破施工技术在城市水工隧洞中的应用,探究了如何进行隧洞静态爆破参数设计、如何进行静态爆破开挖、如何提高静态爆破施工效率与经济性。

Static blasting technology is a new technology for rock crushing and cutting.Compared with the traditional blasting technology,it has the characteristics of no vibration,no noise,no flying rock,etc.,and it has a wide range of applications.Based on Fenghuanghu Tunnel Project in Nansha District,Guangzhou City,this paper introduces the application of static blasting construction technology in urban hydraulic tunnels,and probes into how to design the parameters of static blasting,how to carry out static blasting excavation,and how to improve the efficiency and economy of static blasting construction.
