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由于大型横向位移液化倾斜的地面称为横向扩散。
Liquefaction-induced lateral spreading is defined as the finite, lateral displacement of gently sloping ground as a result of liquefaction in a shallow underlying deposit during an earthquake.
液化诱发侧向传播的定义是有限的、侧向位移稍微倾斜的地面由于液化在一个浅底层沉积在地震中。
As defined by Bartlett and Youd [1], it occurs on mild slopes of 0.3–5% underlain by loose sands where a shallow water table is present.
巴特利特和你所定义的[1],它发生在温和的山坡上的0.3 - -5%而且由宽松的金沙在浅水表存在。
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]。
