Application And Analysis Of Shallow Cut Earth Forced Landing Correction Method Based On Foundation Balance Shaft

The technique of forced landing and rectifying tilting is one of the important methods to solve the problem of building tilting,and also one of the effective means to improve the safety and applicability of tilting buildings.The rectifying of buildings with uneven settlement and tilting not only removes the threat of dangerous buildings to life and production safety,but also avoids unnecessary problems caused by demolition and reconstruction of buildings.At present,geotechnical engineers at home and abroad have done a lot of work on the rectification technology of high-rise buildings,and put forward dozens of technical schemes.According to the engineering experience,geotechnical workers use reasonable means to rectify the inclining of buildings by observing the settlement and inclining of buildings.Through learned through the literature,in the work of rectifying inclination of foundation deformation state study is less,and the foundation base plate in the process of leaning back plane change analysis.In this paper,according to the deformation characteristics of foundation slab in the process of building reversion,the method of foundation balance axis correction is put forward,and the method of controlling foundation balance axis movement is given.A multi-story masonry structure in Handan shallow soil engineering as the research background,using the method of foundation tilting balance shaft straight,rectifying inclination of the project construction,and through the MATLAB data processing software of the monitoring data processing,such as the relative elevation drawing foundation surface,buildings on both sides of north and south,the foundation and the relative height curve and foundation deformation curve of balance shaft rectify leaning method of rectifying tilting effect is analyzed,rectifying inclination of the engineering work.Main research contents of this paper:(1)This paper analyzes the technique of forced landing along with horizontal excavation.In this paper,the elastic deformation and the elastic solution of cylindrical hole expansion are analyzed from the mechanical point of view.(2)Put forward the foundation balance shaft straightening method.Based on the project of a masonry structure in Handan,a reasonable rectifying plan was made,and the monitoring and recording of building tilting and settlement were completed.(3)Process the monitoring data,give the formula of controlling the foundation balance axis movement,and determine the method of foundation balance axis movement according to the corresponding relationship.(4)Guide the construction of a masonry rectifying project in Handan by using the foundation balance shaft rectifying method,and complete the rectifying work.Through the use of MATLAB and other data processing software to determine the location of the foundation balance axis,using the formula and method to control the movement of the foundation balance axis to guide the construction of the building safety reverse work.In the process of rectifying,the effect of rectifying the foundation balance axis is reflected by drawing the change of the tilt amount of the building,the surface of the relative elevation of the foundation and the curve of the deformation of the foundation,so as to realize the safe reversion of the inclined building.
