Tunnel construction management as an important work of daily management, the construction process of the construction materials, machinery and equipment, concrete use of cost control, quality of construction of the tunnel is to achieve one of the guarantees and social benefits. Therefore, from the construction method to the construction of the various elements of scientific control, improve material utilization and reduce costs caused by the loss of working time phenomenon. 

1 A tunnel Overexcavation control means
 
1.1 construction design to accurately measure the loft during tunnel
construction, when carried out in accordance with the scientific design perfect construction supervision, excavation control the distance to try to reduce the error overbreak errors. This requires the construction sector with more advanced measuring instruments, on the basis of precise strategies to strengthen the sense of responsibility mapping education, the results of the measurement and timely feedback.
 
 
1.2 Measurement results and timely feedback, make adjustments accordingly after blasting tunnel section and pre-construction design loft section have a certain gap, work area design data in accordance with the pre-budget overbreak distance, mostly in the actual cross-section staking program , so the design of cross-section according to a predetermined value for construction control, to go through all of the over and under group give accurate measurement data, and construction captain, construction workers and other agreed, good first-hand information, reported to the technical director and director of engineering work area, to facilitate timely decision-making and management.
 
1.3 pairs of daily consumption of concrete and timely feedback to achieve the measurement data proofreading approved, construction technology departments should strengthen the jet, the tunnel invert, tunnel lining surrounding places such as filling and a good amount of concrete used for accurate strictly controlled, arrange special personnel inspect the concrete daily usage, and timely reported to the construction of district director or technical supervisor.
 
2 tunnel construction schedule management measures
 
2.1 Strengthening excavation process cycle times and footage of the assessment of the progress in improving aspects of engineering, construction area combined with pre-construction experience, the project's actual construction conditions that can develop scientific and strict construction personnel appraisal reward system, each team for tunnel construction implementation of the on-site attendance time requirements, adding emergence of convergence from chain or delay construction of the phenomenon, carried out by the parties and the negative sign and acknowledge the responsibility lies. Strict examination cycle shift construction site personnel situation. Are not allowed to leave early, undergo phenomenon. All the time, and tunnel construction progress of construction to be a reasonable plan for improving the enthusiasm of the majority of construction workers.
 
 
2.2 to improve tunnel construction work area traffic management plan according to the construction program and the overall planning tunnel construction situation in each hole large lay aside a go本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
