| Abstract: | Effects of pile pulling on the surrounding structures is a common problem in construction projects.The effect can be reduced substantially if piles are pulled in casing.The overall process is divided into three stages including steel casing pressing,pile pulling,and steel casing pulling accompanied by refilling.We take an abandoned pile in Shanghai Rail Transit Line 7 as an example to study the effect on an established large waste pipe during pile pulling in casing.In the study,we use the general purpose fi... |
