  • THE DYNAMIC BEHAVIOR OF A STEEL PIPE SHEET PILE FOUNDATION IN A LIQUEFIED LAYER DURING AN EARTHQUAKE

    TRUNG Nguyen Thanh , KIYOMIYA Osamu , YOSHIDA Makoto

    …  Various forms of damage to the bridge foundation structure in the revetment along riverbanks and sea coasts caused by liquefaction had been observed during past earthquakes. … However, few studies have investigated the seismic behavior of the foundation in a revetment with a slope. … Therefore, the effect of the lateral pressure of the liquefaction layer on the foundation in the revetment must be investigated further. …

  • Experimental study on prevention techniques for local scouring on river bends

    ABE Sohei , AMADA Takaaki

    … Generally, revetment foundations on straight river sections are protected by constructing bed girdles between the consolidation work, but it is not clear that the bed girdles can play similar roles on bends. … It is known that on river bends with gentle slope, vane works effectively prevent the erosion of riverbanks and the local scouring of river bends. …
