This project is a comprehensive, systematic project, covering the roadbed, bridges, tunnels and so on. Papers considered in terms of construction and engineering characteristics of the premise, the construction of the overall layout, construction plans, labor arrangements set out in detail, for road projects in the works to deal with soft-large, multi-technology; tunnel engineering geological conditions, , And other types of support more difficult re-engineering, the use of DJM, vibro-replacement stone column, early prevention, strong support and other methods to deal with, work out a suitable implementation plan, put forward concrete measures to ensure the quality of the project. During the construction process of continuous exploration and improved in time to adjust and optimize the construction design of the project to ensure the quality and safety of the construction, completion of the project objectives.
