Abstract:

A groundwater control system has been designed to simulate various groundwater conditions in centrifuge tests. The system consists of a water supply part and a control part. A desirable groundwater table can be obtained via a solenoid valve and a feed-back pore pressure transducer. Due to the rotation of a centrifuge model, accuracy in the determination of groundwater table and the location of transducer are discussed. The design of the groundwater control system was verified in a centrifuge slope test and satisfactory results were obtained.

Key words: groundwater control, centrifuge modelling, accuracy of measurement
