Abstract When specimens of different sands are produced using the same preparation method and sheared under conditions (consolidation stress, loading, etc.), while simultaneously keeping drainage closed, resulting tendencies these regarding PWP build-up will be different. This research paper presents a simplified cyclic shear test, which is used to evaluate accumulation in defined specimen proc...

Underground pipelines are widely applied in the so-called lifeline engineerings. It shows according to seismic surveys that the damage from soil liquefaction to underground pipelines was the most serious, whose failures were mainly in the form of pipeline uplifting. In the present study, dynamic centrifuge model tests were conducted to study the uplifting behaviors of shallow-buried pipeline su...

The effects of surface gravity waves on pore-water release from permeable sediment (k 5 1.3–1.8 3 10211 m2) in shallow water were studied in a wave tank. Our tracer experiments demonstrated that shallow-water waves can increase fluid exchange between sandy sediment and overlying water 50-fold, relative to the exchange by molecular diffusion. The main driving force for this increased exchange ar...
