Research On The Quality Control Of Offshore Channel Project For H Cross-sea Bridge

A batch of cross-sea (bay or channel) bridge arises at the historic moment, notonly shortens the gulf people on both sides of the geographical distance andpsychological distance, but also promote the development of regional economy inthe achievement of "China dream" in the great journey, under the background ofvigorously developing the blue ocean economy in countries. Of these, the mostnotable challenge significance is a three-dimensional transport system-offshorechannel, generally by the cross-sea bridge (sea system), offshore artificial island(system in the sea), immersed tube tunnel under the sea (bottom system). This studyfocus on both quality of cross-sea bridge in one hundred, and offshore channel of thesustainable development question, for large sea-crossing channel provides powerfulevidence in the demonstration and operational support.It is very complicated in the whole process about the quality management andresearch of cross-sea bridge(especially offshore channel),it has the very hightechnology content on the bridge construction practice in our country. In view ofmany affecting factors and challenging problems of the quality control for thecross-sea bridge, this study from the theory and operation level, the feasibility oftheory of mind breakthrough innovation and systemic practice method, Throughcase analysis on the quality control of offshore channel project for H cross-seabridge, it makes rational judgment and systemic discussed to guide practice adoptthe method of Collect&archive system, Analysis&Conclusion, analyze, tocombine normative research and empirical research. Aiming at the possible reality of problems in the quality control scheme, theoffshore channel project follows the general requirements of "safe, applicable,durable, environmental protection, economy, advance", Combined with practicaltheory system, puts forward the overall solutions to solve quality problems. The first,Offshore bridge analysis by the theory of whole life cycle cost considerations,consider general control scheme through the whole life cost the economy in theembodiment of the quality control. The second, sea artificial islands use the methodof multidimensional causal analysis to the design level(People), Island compositematerials (Materials), mechanical construction level in the sea (Machine), Marineenvironment (Environment), The integration of a island&bridge water resistance,Island tunnel junction collision avoidance method (Method) and so on many angle toseek quality control. The last, the tube tunnel under the sea adopts the optimumquality cost analysis, through technical methods, such as project risk perspective, fortunnel under the sea usually adopt the immersed tube tunnel and shield tunnel ofoptimal quality cost analysis and scheme comparison for the scheme of optimalquality control.It is difficult to deal with the phenomenon in view of the constructionmanagement practices of some chaos, such as poor quality management system,construction of subcontract, the lack of effective supervision during construction,ignore the quality problem for multiple deadlines and to reduce the cost of reducingconstruction standards, and so on.H bridge sea channel in the practice of the quality control, analysis the qualitycontrol process from the perspective of comprehensive, support and lean, That TotalQuality Management (Research and demonstration, planning and design,consultancy and advisory, construction and operation), Quality Operation Support(quota list, form a complete set of special, special libraries, project specification),Lean Quality Control (key technique, design scheme, construction organization, operation manual), its core idea is to organize respectively hub, the standardization,operation quantity and price factory.According to the system theory of quality control and mature practice, H bridgeoffshore channels were the effect of project quality control efficiency is significantlyimproved, and form a "comprehensive and dismantling integration" applicationmode.The innovation of this study, not only put forward Quality control scheme,process and effect, bring certain guiding significance for problem solving afterbuilding longevity, is also the sea channel sustainable development direction in thefuture. And put forward the modern quality management theory and practice that"low-end built " towards "high-end manufacturing" and from "makes thehigh-quality goods" to "Century structure" for large sea-crossing channel providespowerful evidence in the demonstration and feasibility.Convergence "positive energy","China dream".
