Abstract :
Plenty of unconfined compressive shear tests were performed on reconstituted clays from shield work well of wuxi subway tunnel mixed with cement to investigate the effects of water content, cement content and curing time on the strength behavior of the cemented clays. A formula of unconfined compressive strength is proposed by fitting the examination data of cemented clays. The strength formula proposed in this study can be used for derivation the cement-pure soil ratio with the knowned unconfined compressive strength,the strength formula can also be used for predicting the unconfined compressive strength,based on certain conditions.
