During past earthquakes, many important structures supported on pile foundati have been subjected to severe damages due to large lateral displacements of liquefied sloping ground termed as lateral spreading.
在过去的地震,许多重要的结构支持桩基础受到严重的损害赔偿Such soil deposits are prone to excess pore water pressure generation, liquefaction and cequently large lateral displacement during seismic excitati.
这种土壤存款容易超孔隙水压力生成、液化和因此大侧向位移在地震波。
Horizontal displacements in a lateral spreading can be up to several meters which can equently impose substantial kinematic forces to pile foundati causing extensive damages.
水平位移的横向传播可达几米可因此造成了重大的运动部队造成广泛的损害桩基础。
Several examples have been reported during past earthquakes in this regard, among which the 1964 Niigata, Japan, the 1989 Loma Prieta, USA and the 1995 Kobe, Japan, earthquakes are the most destructive [2], [3], [4], [5] and [6].
几个例子被报道在过去的地震在这方面,其中1964年的日本新泻在年洛马普列塔、美国和1995年日本神户,地震是最具破坏性的[2],[3],[4]、[5]和[6]。
