On the quality control measures of concrete diaphragm wall construction

With Subterranean project development,much deeper diaphragm wall subject appears.

Underground diaphragm wall had been great used in enclosure structure of subway and deep foundation.

Based on the study of underground continuous wall of Nanjing Yangtze river tunnel,this paper analyses under-ground continuous wall construction procedure on Nanjing Yangtze river flood land,and the successful experience of con-straction can be referred by other similar projects.

The continuous wall technology of pile made with cement jetting-milling was proved economic and effect for WR project seepage prevention, embankment strengthening and foundation seepage prevention.

The mitigation effect of WIB,continuous wall and open trench were compared.

Convenience in the work of calculating continuous wall beam is offered,which provides a hasis for reestablishing the new code of masonry.

A special finite element method program is compiled for the continuous wall beams in this paper.

In order to analyze continuous wall beam, a special finite element method program (QLF) adopting 8 nodes isoparameter element has been developed.

The common problems in the construction of underground continuous wall and the management;

Research on the quality control points of underground continuous wall;

Analysis of effect of different membership function on calculation of fuzzy reliability in underground continuous wall;
