Abstract


Because of the particularity and complexity of geotechnical engineering, consider the tank group can affect the stress and deformation of the foundation group of tanks in the application of design and construction is still in the research and exploration phase. In practical engineering construction group can often overlook the effect of group can be considered an accident caused by many projects, especially in soft ground. Construction of storage tanks in the soft soil, the preloading filling rate of the control and calculation of excess pore water pressure tank group to consider the foundation soil under the effect of stress and strain analysis of critical and difficult.This paper studies the numerical simulation method, pre-filling water pressure loading rate and soil - structure interaction flow model is the modeling and description of the key and difficult.Based on site investigation of soil samples extracted, indoor geotechnical soil parameters obtained from experiments, numerical simulation software on the storage tank excess pore water pressure in soft soil formation mechanism and the effect of group was simulated tank. First application of FLAC ~ 3D software, consider a single tank in the theoretical design of the preloading filling rate established under the soft ground of three-dimensional solid model for finite difference method, can touch the bottom and the soil is simplified as completely elastic contact, of soft The foundation of single cans of stress and deformation. Then, in the FLAC ~ 3D software flow module, the application of soil and flow coupling theory, the spacing by changing the tank, the tank arrangement of rectangular tank in the group of the foundation under the effect of stress and deformation and soft soil changes in the mechanical condition of the foundation caused by the excess pore water pressure and the stress superimposition between the storage tank on the tank design and ground clearance of stress and deformation. So as to arrive at the site considered for fire protection and engineering group obtained under limited conditions optimal spacing can design and soft excess pore water pressure and excess pore pressure ratio of the formation mechanism of water-filled tank at the same time draw preloading the impact of the rate of soil depth and scope to effectively control the actual project design and construction. Finally, with a sales company in Tianjin Dagang practical engineering analysis and numerical simulation of the accident site measured data were compared to arrive at the accident led to the project the main factors, including the following two factors. Partly because the clearance of the project tank is too small, on the other hand is mainly due to excessive charging rate of the preloading may be an accident for the project to provide guidance based on corrective programs.In this paper, consider the group of tanks on the tank under the effect of stress and deformation analysis of foundation for the future design and construction of similar projects to provide a reference value.
