Research Of Embedded Later Enlarging Pier Replacement Construction Technique For Zhao Yang Building Project

the article offers the concept of embedded later studies the technique ofembedded later enlarging pier, offers the point of the author to the design, calculateand constructions of enlarging pier. Especially on the research of applying depth ofshallow foundation theory. The dead weight of foundation earth becomes a permanentvalue when the depth arrives the fixed value D, doesn`t increase by the increasing ofdepth positively proportionally. We offer calculation formula to calculate pierlaminate on the basic of shallow foundation theory. The author analysis themechanism of oblique anchor wall with power. And researches the design calculationmethod when the expanding part expands in the hardpan.On the base of practicallycases, the author offers the explanation on the construction and attentions forembedded later pier replacement construction, attain prospective economy andsociety benefits .
