Study On The Mechanical Characteristics Of Bridge Deck Reinforcement By Planting Bars

The technology of rebar planting with chemical grouting is reinforcement technology of more effective, convenient, quickly and economical, from its ancient origins to the present day, which being applied more broadly in actual engineering through decades of years. This technology has done pretty well, especially for structural consolidating and widening, buried wrong place or losing buried problems.The study of reinforcement implantation in early periods inclined more towards the pull-out experiments study and made a lot of research results. Even though there has study of lap by Planting bars and population for anchorage effect, the relative case,results and theory of study is not so much. The study on the bridge can be seen in slow test by lap for Planting bars beam, and it is also effectual in analyzing plant type structure. This paper is concerned with bridge deck’s bearing capcacity of reinforcement implantation by means of combination of experimental study and theoretical analysis on a background of actual engineering. This thesis consists of three parts:Through slow test with well-connected component in laboratory, working the stuff of lap for bonded-rebars by Cantilever slabs. In the experiment, the test phenomenon and data had been observed and recorded in detail. Based on the data, to explore the causes of these phenomena and influencing factor, it should analyzing the deformation of reinforce plate, failure mode and ultimate bearing capacity during the experiment.Based on the test data and parameter, aimed by the finite element software ANSYS,it simulate the actual test process which considering the situation of Planting bar for bond-slip, and analyzing comparison between the calculated results with the test results to verify the test exactness.Based on experiment and data of the theoretical analysis, combined with some research achievements of other personnel, introduced a enhancement coefficient for deflection, to put forward more effective calculation of bearing capacity and deflection with plate type structure by Planting bar.
