Summary on Grant Application Form |
|
There is considerable uncertainty concerning the lateral stresses for which embedded retaining walls in an overconsolidated deposit must be designed, with the results of recent research providing conflicting but incomplete evidence. One reason for this is the absence of case records in which the behaviour of both the wall and the soil have been monitored continuously throughout all stages of construction and service.It is proposed to investigate this issue by means of a comprehensive programme of monitoring, back analysis and interpretation of the behaviour o the retaining walls for the cut-and-cover tunnel that will take the Channel Tunnel Rail Link under Ashford in Kent.A key aim of the proposed research is to link the behaviour of the wall to the state of the surrounding ground. It is essential that earth pressure cells are installed in advance of the wall, to establish the in situ stress state of the ground and monitor stress changes during wall installation.This initial application to EPSRC for funding is to cover the cost of installing earth pressure cells, which will be used to assess the impact of wall installation on lateral earth pressures and how they should be taken into account in design.
