Comparison and selection of foundation pit support in water-rich weak stratum and analysis of deformation law
This paper takes the ramp foundation pit of a coastal traffic comprehensive reconstruction project as the engineering background,obtains the horizontal and vertical displacement and supporting internal force of piles(walls)with different supporting structures through on-site instrument monitoring,analyzes the deformation law of supporting structures according to the project working conditions and geological conditions,and formulates solutions and guides the follow-up engineering construction according to the kicking deformation problems,which provides a reference for the selection of supporting forms,the construction of supporting structures and the safety risk control of surrounding environment in deep foundation pits under the conditions of rich water and weak stratum.
