The filter cake on the tunnel face has a significant influence on project of the slurry-driven shield. During the excavation, only permeable filter cake is allowed to form because the rotating speed of cutter wheel is fast. Through the filter cake, the water of slurry will infiltrate into the soil. The water enhances the hydraulic head and the risk the failure of tunnel face. In order to determ…

A series of marine atmosphere exposure tests were planned and started in 1976 on prestressed concrete prisms which were post-tensioned with unbonded tendons. The objective of these tests was to investigate the corrosion behavior of a grease and plastic covered prestressing strand and anchor fittings for unbonded tendons embedded in concrete. The test duration was originally planned for five yea…
