Study of technique of soft ground damming of protection embankment for Tianjin North Boundary Power Plant

The suitable structures of protection embankments are proposed after analyzing the reservoir operation,land configuration and foundation structure.

In this paper design principle and problems in construction are analyzed aiming at design and construction of protection embankment.

This paper presents the important achievements of the safeguarding of stress corrosive cracking of ammonia spherical tank,the building of protective cofferdam and the continuous detecting and monitoring systems engineering against the leaking of ammonia spherical tank.

<Abstrcat>The cost to construct the permanent engineering, which is for preventing the bank from flood using current normal method of construction on riverbed made of sand,is too high to be accepted.
