Tunnel Mode Custody And Reasonable Cost Study

At present, China’s tunnel management uses the enterprise operation, we have made some achievements, We were influenced by "heavy construction, light management" traditional thinking.there are still some provinces calculate the cost of maintenance and repair neither conservation Fixed did not estimate index, so that the calculated cost of maintenance and repair unfounded; So how to make the management and maintenance of road tunnels more rational,and how to calculate in the absence of maintenance and repair of the disbursement basis, these two aspects is the key issue of highway tunnel management and maintenance unit to be addressed.Therefore, Therefore, this paper Shenzhen tunnel to study the basis of conservation. In this thesis, the following: Fist, This thesis analyzed the domestic operation and management model representative of the tunnel, the tunnel of Shenzhen City to set the current management structure and mechanical conditions, staffing, proposed a reasonable mechanism for Shenzhen tunnel operations management configuration.Secondly, In this thesis, the factors affecting the cost of maintenance and repair of recognition on the interpretation of the structural model was constructed road tunnel maintenance cost influencing factors(ISM), and to identify the most important factors that influence the cost of conservation. Third, This thesis analyzes the daily maintenance cost of the project criteria and calculation methods Shenzhen highway tunnel civil structures; and preparation of the "Shenzhen Daily inspections fixed" and "Shenzhen accidents enclosure quotas." Fourth, In this paper, maintenance and repair costs associated with the establishment of a number of lanes, traffic years, traffic volume forecast model. Fifth, This thesis analyzes the growth of labor costs, material costs growth, Jixietaiban growth, and made a calculation method to determine the maintenance and repair costs increase coefficient.
