Performance Assessment Of Cut Off Walls Subject To Tidal Variation

Antony Orton

Cut off walls constructed in coastal settings are subject to external tidal variations in water pressure. A method to exploit this tidal variability to check the performance of cut-off wall construction is presented supported by analytical and numerical modelling results. The method described allows progressive assessment of performance of the wall during its construction. The approach is illustrated with reference to two case studies: one for a major building project and the other for an environmental control measure.
