Top-Down Method Technology In High-rise Building In The Applied Research

Top-down method Construction and Design Theory for this paper, specific examples ofprojects rely on Top-down method Construction and design a detailed argument expounded aimsto provide a degree of role in guiding the future construction of the Top-down method.To thisend,the main concent of this study are as follows:(1) A brief description Top-down method the background and significance of thistechnology, development in the world, the basic principles of classification and characteristics ofthe Top-down method,draw Top-down method currently exist in the design and construction.(2) Detailing the Top-down method design and construction of a number of keytechnologies, in particular the building envelope construction and design, earthwork excavationdug way settings were described in detail.(3) Top-down method analysis of finite element theory. Including finite element basicprinciples of finite element analysis step, the constitutive model of soil, Top-down method finiteelement network simulation of the excavation process.(4) Combined with specific examples of the use of MIDAS/GTS software Top-downmethod Construction Engineering simulation, analysis with the construction of pit soilexcavation and basement structure, the pit outside the settlement of the soil changes thedeformation of the diaphragm wall, the bottom soil body to uplift the law according to theestablishment of the column changes, summarized. Reach to ensure the security, optimization ofdesign guidelines for construction purposes, and Top-down method the practice of constructiontechnology recommendations, and provide a reference for the design and construction.
