Study On The Numerical Analysis And Application Of The Excavation Of The Masonry Structure

The problem of building inclination has existed for a long time.Relevant experts and scholars at home and abroad have also achieved fruitful scientific research results and effective theoretical system,thus promoting the steady development of inclination correction technology.In the course of rectification of building inclination,geological exploration,structural detection,scheme selection,construction technology and post-monitoring are inseparable.At the same time,stability and safety in rectification is the key to the whole rectification construction.This paper reports the research status and development trend of inclination rectification projects at home and abroad,lists various internal and external causes of inclination of buildings,makes a thorough analysis and Research on the technology and characteristics of inclination rectification and reinforcement of buildings,and the control of the inclination rectification target of buildings is the overall control of the whole scheme design and even the inclination rectification construction.In the course of rectification,we should take the relevant national standards and norms as the benchmark control target,the anticipated control as the guidance,and the stability evaluation as the restriction,so as to make the rectification process proceed steadily and orderly.For a long time,most of the theories of rectification are based on the study of the respective structures of houses,and seldom take into account the synergistic deformation among the superstructure,foundation and foundation.In the course of rectification,if we ignore the influence of the interaction among the three on the plastic area of the soil around the hole in the excavation area,it is bound to be inconsistent with the actual situation or even draw wrong conclusions.The theoretical analysis of the interaction is carried out,and the influence trend and the correlation of the three are studied.Based on the rectification project of a six-storey residential building in Hebei Province,the design and optimization of the rectification scheme are elaborated,and some key procedures of reinforcement design and rectification design are described in detail.In the model analysis stage,the actual geological conditions and model size of the project are taken as the carriers,and the numerical analysis of the whole structure before and during rectification is carried out by using ABAQUS finite element analysis software.In the rectification analysis,the charts and data of the horizontal direct and oblique excavation stages are sorted out,and the fluctuation trend of the secondary settlement in the corresponding stage and the analysis conclusion are obtained.
