The Monitoring Of Tunnel Blasting And Vibration & The Research Of Construction Technology

With the rapid development of tunnel in our country, more and more new tunnels will be put under the existing traffic lines. Because of the special terrain, geological conditions and route, the problem is more and more, such as the problem of the difficulty of the construction of the new tunnel, the construction of the new tunnel, the influence of the new tunnel, and the research on the mechanism of the damage. The interaction between the two jobs is currently in urgent need of solution.Most of big development has always been to Phuket cross cat Gong Ba large section tunnel left line export Buji water supply tunnel, the tunnel invert construction when the excavation surface distance water supply tunnel top surface recently at only 3.7 meters, and invert excavation by blasting construction. The tunnel construction is very rare, and three lane and four lane large section highway tunnel portal section construction of tunnel construction in the danger zone, which gives us a great difficulty in construction, but also the very rare.With China's transportation infrastructure construction, the road to the tunnel with three lanes,four lane section development trend more and more obvious, and the monitoring of the impact of blasting on adjacent buildings will be more and more, through this research, such as the research results can be applied to similar large section tunnel blasting monitoring, will generate huge economic benefits and social benefits.This topic research significance lies in for the surrounding rock of the tunnel blasting excavation stability research and determine the reasonable construction method, through research projects for the level of shallow hole blasting data parameters. The results direct service in the economic construction of Shenzhen; of tunnel excavation vibration monitoring,determine the reasonable construction method, regression analysis of data, research on tunnel stability. Combined with the blasting vibration monitoring research, through the monitoring data of blasting parameters are adjusted to ensure construction safety. Research results can be application in the similar tunnel construction. The income conclusion of Mao Gong dam of large section tunnel The construction and monitoring of the road section provides a certain technical guidance, and also provides a reference for the similar shallow buried highway tunnel support parameters and construction methods. The application of this research will not only improve the level of the construction of the enterprise, but also promote the development of China's tunnel construction technology and national economy.
