Research On The Displacement Of A Dumper Shed Round Diaphragmat Coal Terminal Of Tianjin Port

This paper combines with the project of Round Diaphragm of Car Dumper Shed which inNanjiang Coal Terminal of Tianjin Port analysis and study of structure sensitivity characteristicof round diaphragm wall. Through analyzing the data of locale test, the phenomenons of overallinclination which occur in the construction process of round diaphragm wall's supportingstructure are obtained. Through the data results of the round stress of the round undergrounddiaphragm wall and beam, the stress behind wall and vertical steel bar of undergrounddiaphragm wall, we can find that when the phenomenons of overall inclination occur in theround diaphragm the distribution stress of diaphragm is dissymmetry. Error of construction playanimportantroleinthestructuresensitivitycharacteristicofdiaphragmwall.According to the example project circumstances, use the application of Fast LagrangianAnalysis of Continua (FLAC3D) to set up numerical modeling. Considering the influencingfactor of pit construction we can found that in the dissymmetrical dig condition thephenomenons of overall inclination occur in the Round diaphragm and the bend deforming issmaller. Compared between the data of locale test and numerical value simulation, such as thedisplacement of round underground diaphragm wall, and the internal forces of supportingstructure and the earth pressure behind the wall, analyses the distribution stress of supportingstructure. When the phenomenons of overall inclination occur in the Round diaphragm, localstress aggravating of diaphragm wall is obvious. useing date of the performance data andnumerical modeling of two distinct work condition , analyzing foundation stabilityand endogenforce of diaphragm and distribution of earth pressure and structure sensitivity characteristic ofdiaphragmwall.Theresultofthispapercangivesomereferencetotheanalogousproject.
