Application On Treatment Methodof Reinforced Building Foundation

The reinforcement of the existing buildings is very important in both the building industry and economic life of our country,and it is the important foundation work for the recovery,perfection and enhancement of the building’s functions.Because of the increasing load,thechanging use,problems emerging in investigation,design,and construction,etc.,there are quite a number of existing buildings requiring reinforcement treatment. Although a lot of research has been made on the treatment of building foundation reinforcement,and many kinds of methods have been put forward,the stress is usually laid on the construction machinery and technique.In other words,the fact that to thoroughly analyze the mechanical characteristics of the resistingforce of the building is the premise of choosing and optimizing reinforcement is often neglected.Therefore,it is of important practical meaning to carry out research on resisting force of building foundation before reinforcement.Based on the research of building foundation reinforcement and its application in construction both at home and abroad,the thesis first discusses the causes and manifestations of those accidents resulting from poor quality,and how to identify and evaluate the original building.Then,the paper summarizes four principles of building foundation reinforcement,namely,exploiting the potential of building foundation,accurately calculating the load of foundation,giving priority to the adoption of measures that improve the integral rigidity of the structure,and the adoption of simple structure.At last,the paper introduces the treatmentmethods of reinforcement in common use at present.In this paper, according to the appearance of damaged buildings, intended reinforcement programs, and develop a detailed implementation plan, and the detection and monitoring have also been described, after the completion of the construction process.Wanted to be able to provide examples comparing the systematic research foundation Retrofitting by Existing Buildings, and playing a certain role model for practical engineering.
