| Through studying of numerical simulation using EverFE of finite element and Flac3D of finite difference method software to bridges channel and foundation, this article put forward a reasonable and economic structural concept for roads and bridges channel, according to Lot X Hangzhou Bay Bridge project by the 800t tire removal machine Box program and moving the device to go on roads where the region's geological conditions。First, the article introduces Lot X Hangzhou Bay Bridge general condition of project。The deformation of pre-site base is so strict because pre-Box games and handling machine is very heavy in precast yard and the pre-site base is soft。If handled properly, it could cause the construction of the overall instability of pre-market or making and storaging beam seat deposit impact the quality of box beams because of too large deformation。Secondly, according to simulation analysis of finite difference method software FLAC3D sites on the pre-field ground-based, it could obtain the site of the most dangerous areas and analyze the transport machine at work on the deposit beam seat and pedestal foundation of beam impacting。The pile head under load and the soil around the pile are produced on the basis of friction piles while load covere in the pre-field case。Thirdly, the article calculates the pavement structure on the vertical and horizontal beam transportation channel by EverFE and taking into account the dynamic load, partial load and the cumulative effects of fatigue produced by interaction。Longitudinal girder channel programs should be selected the best one in several pavement structure and horizontal girder structure of the program is feasible because its maximum tensile stress within the each block panel does not exceed the tensile strength of concrete; also we should note dowel bar and rod set。Finally, according to the research paper, we can draw some practical conclusions on the project and some suggestions for future work to carry out the same help。... |
