Abstract
Several earthquakes in the 1990’s revealed the problem of significant subsidence of river dikes induced by subsoil liquefaction. Although soil improvement is the most reliable solution to avoid the onset of liquefaction, the substantial length of liquefaction-prone dikes together with the economical reasons does not allow this solution. It is aimed, therefore, to mitigate the subsidence to a certain extent so that a fatal flooding is avoided. The present study examines the possibility of installing sheet pile walls at toes of river dikes. Shaking table tests were conducted for this purpose and the effects of sheet pile walls were studied. Moreover, a combination of walls and drains for quick dissipation of excess pore water pressure was investigated.
