Abstract
Instrumentation has been installed to monitor the behaviour of a bored pile retaining wall with a stabilising base during and after its construction of the Coventry North-South Road scheme in Warwickshire. Wall movements, wall and base bending moments, loads in the temporary props, and vertical pressures beneath the permanent stabilising base were monitored. In this report, the ground conditions, construction sequence and instrumentation are described and the field measurements during construction and its first two years in service are discussed. The results are compared with a finite element back-analysis and outline recommendations made for the design of similar structures in the future. (A)
