Five Topics in Subgrade and Foundation Design/Lu Peijun(Tongji University,Shanghai 200092,China)
Abstract:Five problems which are the applicability of static pressure piles,the pressure of basement board,the settlement controlling of multi story and high buildings,the inclination and decentration and the application of composite piles foundation controlled by settlement,are encountered frequently in the design of the subgrade and foundation engineering,especially in soft clay areas.Analysis and interpretations of the problems are conducted based on the technical specification,the theory,the site observation and the construction practice.It is instructive for the structural design.
Keywords:static pile;compression;raft foundation stress;settlement controlling;eccentricity
