| At present, our country has been completely with the independent design and manufacturing Earth Pressure Balance shield, Slurry Shield tunneling and the ability to Composite shield, developed by China Railway Construction Heavy Industry Co.LTD, the domestic first TBM is in Jilin YinSong project success application, our country’s ability to design and manufacture of tunnel boring machine has already reached the world’s top level. But there is a certain gap on the site construction management, while the accumulation of a wealth of construction experience, but the basic research is still at the initial stage, close to the practice of engineering research is less.This thesis is a part of the research project of Shijiazhuang metro construction quality management, and mainly carries on the research of the quality management. To control the construction zone face high ground as the prerequisite for science-related driving parameters set, shield tunneling driver’s operating system reliability analysis and optimization.Earth pressure balance shield tunneling quality management, first of all to maintain the excavating surface stability, improved soil mass flow of the plastic, the last of the shield tunneling parameters reasonable setting. By building and analysis of the maths model and the parameters of soil pressure, cutterhead torque, the total thrust setting largely by equipment in the influence of buried depth, soil properties, and a certain positive correlation between the parameters.Combined with the construction of interval prophase of shield machine PLC equipment to collect relevant data, application of SPSS and OriginPro data analysis software, the construction parameters and the measured values for the parameters of statistics, linear regression analysis and comprehensive analysis and contrast modulus conversion, validation analysis about the conceptual model, mathematical model. Objective to provide theoretical reference for shield tunneling driver operation, avoid objective errors occurred.With the Human Factors Engineering are widely used in various fields in our country, research on shield driver with more reliable and direct research. Combining with the tunnel construction environment and the operating room, this paper makes a scientific research and summary of the professional ability, visual fatigue, physical fatigue, mental fatigue, physiological state and psychological state of the shield. Applied the fuzzy mathematics theory, the expert weight grade method, the survey and interview method, the mathematical model method, the observation statistics method, and proposed the related optimization plan,effectively reduce shield driver subjective errors. |
