"City Of Dreams" Basement Anti-float Design Based On Force Balance Method

In practical engineering,due to the complex geological situation and the different basic forms,the anti-floating problem of the basement structure has always been the top priority.Therefore,carrying out a mechanical analysis on the basement floor which is undertaken water buoyant force directly and designing it has theoretical and practical significance.The main content of this article is as follows:In this paper,the related research background and significance,the failure of the status and the common anti-floating designs of the basement under the effect of water buoyancy are summarized;the common anti-floating design methods and the specific rules and regulations in relevant operations are generalized;the understanding and research development concerning the anti-floatation of the basement both at home and abroad are concluded.The loading characteristics of the basement under the force of water buoyancy is figured out by analyzing the loading process of the basement with the method of combining theoretical analysis and numerical simulation,adopting the elastic thin plate bending theory,carrying out the theoretical calculation based on the typical grating area and using the elastic phase contrast analysis and numerical simulation to get the analysis result.With the combination of the theory of concrete structure design,the general method of anti-floating design and the calculation method and structure design process of the basement floor are summarized after a general discussion of the methods from four major aspects of design,structural analysis,component design and construction drawing."City of dreams" by covering the engineering background of the basement,in the design stage,based on the force balance method,the selection of suitable the anti-float anchor,surplus YJK architectural structure calculation software is adopted to establish the structure calculation model and a preliminary trial,analyzed the structure and basement anti-floating analysis,according to the structure analysis to get the most adverse internal force for independent foundation,anti-floating anchor rod,the design of the floor,finally draw the related structure construction drawing.
