GTS Simulation And Comparative Analysis Of The Ultra-deep Foundation Pile Anchor Retaining Structure

With economic development, the increasingly rapid process of urbanization, the growing demand for the development of underground space. Birth of a growing number of ultra-deep pit in the geotechnical field. Ultra-deep foundation pit during the design to ensure that not only in the construction the pit of solid security, as much as possible material savings, so can largely cost savings. This paper studies the ultra-deep foundation in a common support structure-pile-anchor retaining structure. A typical pile anchor retaining article mainly combined with the end of the village, Shijiazhuang Cassia Phase transformation in ultra-deep excavation engineering area, specifically the main contents are as follows:(1) Of domestic deep foundation of current research and finite element numerical simulation method is described and summarized in the pit design application, and then describes the content and method of this topic;(2) Introduction to the characteristics of the care system, working mechanism and failure modes and causes of pile-anchor the same time, through access to relevant information, analyze and summarize the calculation method of pile-anchor retaining structure design, and engineering instance Lizheng analysis software and the corresponding the formula calculates the engineering examples pile-anchor retaining structure pile displacement, earth pressure, shear, according to the calculation results summary analysis. Put forward some feasible suggestions for the project;(3)MIDAS/GTS a brief introduction, and then from the process of the operation, the analysis capabilities of the software as well as the material model MIDA/GTS described. Subsequently, MIDA/GTS model of Shijiazhuang, a super-deep pit, MIDAS/GTS actual engineering numerical simulation using finite element stress from the soil, the deformed, the deformation of the pile, the shear and bending moment, the anchor of the axial force and other aspects of a comprehensive analysis and research, and monitoring data were analyzed, and the corresponding conclusions. Actual engineering design and construction of the research recommendations of the feasibility.Concluded that the actual engineering calculation:and management is calculated and compared to the actual monitoring results, MIDAS/GTS simulation results for Anchor Piles Bracing reliable. Using MIDAS/GTS pile-anchor retaining structure analog design is feasible.
