| Research Abstract |
This research examines the pore water pressure profiles in deep sedimentary ground. The field observations indicate the pore pressure changes by a depth of 402 meters below the ground surface are affected by atmospheric pressure change and the lunar attraction etc., and the principal factor affecting the pore pressure change is local pumping. A three-dimensional coupled soil-pore water finite element system to simulate the deep ground water flow was proposed. The analytical results explain an environmental-impact related to the excess pore pressures generated in deep ground.
