Summary on Grant Application Form |
The co-ordinated programme of research will involve the monitoring of retaining wall movements and prop loads during construction of an underground car park. Four vibrating wire strain gauges (with built-in thermocouples) will be attached to each monitored prop. In addition, thermocouples will be attached directly to the steel props to quantify the effects of temperature on prop load development. Strain gauges and thermistors will be monitored continuously using a multi-channel data logger. Inclinometer tubes will be installed within the monitored section of the retaining wall, enabling the deflected profile to be measured. Target points will also be located at the crest and at points down the length of the wall to monitor wall movements with reference to remote bench marks using precision surveying techniques.The measured prop loads and wall movements will be compared to the design calculations and analyses used in the original design. Back analyses of the observed performance of the wall will be undertaken, using the finite element program CRISP95. It is considered that this site complements on-going research at Canada Wharf and Canada Water Jubilee Line Stations, because the present excavation is almost wholly within London Clay.
