Retaining Wall

Hi All I am doing preliminary design of Contiguous Bored Pile wall for Crossrail project in London.The soil stratum is 1.5-2.0m thick made ground and 20-25m thick London clay.I adopted 1050mm dia pile @1150mm spacing.The retained height varies from 6.0-8.0m.I am getting 44-50mm as short term movements and 95-100mm as long term movements.There are existing Viaduct foundations near proposed retaining wall.Are there any allowable criteria for deflection and movements of retaining walls? Thanks Debasis

It is very important to have proper drainage behind the wall as it is critical to the performance of retaining walls. Drainage materials will reduce or eliminate the hydrostatic pressure and will therefore greatly improve the stability of the material behind the wall, assuming that this is not a retaining wall for water.
