基于微型桩托换的建筑物基础加固设计
Building foundation reinforcement design based on micro pile underpinning
摘要
Abstract
Uneven deformation of the superstructure will affect the safety of engineering structures, and the reinforcement design of foundation and the use of reinforcement are important measures and content to control the increase of foundation settlement and to ensure the safety of the upper structure. Concerning the phenomenon of larger settlement of a building,by analyzing its stratum,data structure of building and foundation settlement data,the paper discusses the causes of structure foundation settlement and the overall tilt by the loess collapse under the bottom of foundation,deep soil loading foundation around and the negative friction of the side of column caused by backfill etc.Based on consideration of settlement control and the site environmental conditions,we propose that the upper structure load be transferred to the lower strata by micro pile in order to control the purpose of settlement.关键词
