effectiveness of diaphragm wall in reducing the potential of soil
liquefaction induced by earthquakes in time domain. The influence of
the dimension of input motion, and the intensity of input motion, on the
obtained results is investigated first, and then the effectiveness of
diaphragm wall in reducing the liquefaction potential is studied by
varying the young’s modulus and embedment depth of wall. It was
found that in three dimension analysis, the 3D input motion should be
used, and the larger input motion is the faster the excess pore pressure is
generated. It also found that with appropriate design, the diaphragm
wall can be effective in preventing liquefaction, and reducing settlement.
