The Study Of Ma-Gou Bridge Construction Constrol And Manage Technology

This paper is with the Ma—Gou Bridge. Study the things , make the whole course of construction of the Ma—Gou Bridge as thread , build the scheme and make policy on the Ma—Gou Bridge , concrete quality control of the Ma—Gou Bridge , have such questions as the Ma—Gou Bridge construction method and operational procedure have controlled , constructed the cost and managed and controlling and becoming performance rating of the bridge relatively gone on deepenning systematic research , the main research results are as follows :(1) Potentiality of carrying capacity to choose the bridge . length of the bridge , fabrication cost of the major project , interim project expenses . construction complexity , bridge beautiful . time limit for a project called , maintain and maintain terms , is it flow 9 index of of requiring etc. to pass later stage time limit for a project , ration of the index and standardized treatment of every index through determining the nature , is it in [0 , 1 ] interal , use grey related law and improved grey related law to limit every index person who fetch , have calculated related degree each building the scheme and consulting the scheme (or ideal scheme ) separately , it expresses the quality of the scheme that big or small with related degree , thus realized that builds comprehensive decision of the scheme to Ma-Gou bridge .(2) Have probe into the relation between structure quality and reliability , has pointed out that the course of the structure construction carries on the necessity of quality control , and has proposed that a kind of concrete based on grey systematic theory is grown course quality controls the method to predict greyly and control dynamically. Is this kind of method through walking systematically ? The materials are arranged , look for and do systematically, the laws of the development and change , according to the law that has already been grasped , predict system walking in the future。Walk according to the system in the future predicted value , take the control measure.(3) Combine Ma-Gou bridge's actual conditions , begin from the foundation of the underpart structure until case prefabricating , key construction process of the important position that installation and bridge floor decorate etc. of roof beam of the top structure has relatively gone on systematic exposition , has analysed the quality existing while constructing and potential safety hazard, and provide the concrete treatment measure 。 A lot of conclusions drawn have certain reference value to the construction of the similar bridge .(4) The cost managed and controlled the law construct with the special project is the foundation , the brief basic conception that has introduced the project cost of the highway and managed and controlled, construct hierarchical structure , cost of management system , set up...
