In order to calculate the ground movement induced by displacement piles driven into horizontal layered strata, an axisymmetric model was built and then the vertical and horizontal ground movement functions were deduced using stochastic medium theory. Results show that the vertical ground movement obeys normal distribution function, while the horizontal ground movement is an exponential function...

tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. the predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. the commonly used earth pressure balance (epb) tunneling machines, uses the excavated soil in a pressu...

Airports all over the world are becoming busier and many of them are facing capacity problems. The actual airport capacity strongly depends on the efficiency of the resource utilisation. Although simultaneously handling all of the problems may result in more effective resource utilisation, historically different types of airport resources have been handled independently. Despite introducing new...

A recent Wall Street Journal article by Arthur C. Brooks on the Occupy Movement and fairness («Fairness and the ‘Occupy’ Movement, November 25) says some interesting things about potential common ground between free-market ideas and the Occupy movement. Yet Brooks also commits some very important errors. Perhaps with clearer facts there could be more common ground on reforming the economy and p...
