高擋土板樁墻施工期三維整體有限元數(shù)值模擬
[Abstract]:Based on ABAQUS, a 3D finite element integral analysis model of the wall plate pile structure of the shiplock is established, and the corresponding FRIC subprogram is developed to simulate the interaction between the ground connecting wall and the soil. In this paper, the internal force, deformation and the internal force of anchor rod are continuously simulated by 11 grades of Anchorage piles in five typical stages during the construction period of shiplock, and the results of numerical simulation are compared with the measured results in the field. The layout height of anchor rod and the excavation mode of the sluice chamber soil are studied optimally. The results show that the whole analysis model can accurately predict the deformation of the anchor pile, the deformation of the ground connection wall and the change of the internal force of the anchor rod during the construction period, and the excavation process of the sluice chamber soil has a great influence on the displacement of the ground connecting wall and the Anchorage pile. The deformation and internal force of the wall are minimized when the anchor rod is arranged 2 / 3 of the height from the mud surface to the top of the gate.
