强震作用下地面的变形和破坏是一个广泛的震后效应。它直接危及广大人民群众的生命财产和工程设施的安全。工业和民用的厂房、军工设施、地下建筑、铁路、公路、桥涵、农田水利设施和水工建筑物、海底通讯设备等等,在强震作用下由于地面变形而破坏的,比比皆是。强烈的地震,常常因为地面的强震效应使地震的灾害大大地加剧。例如,1960年智利地震(M=8.5)主要的震害是由于山崩和滑坡引起的,最大的滑坡体达3000万立方米;1964年美国阿拉斯加地震(M=8.6)时,半岛中南部的公路、桥梁和港湾设备因地
The deformation and destruction of the ground under the action of strong earthquakes is a broad post-earthquake effect. It directly endangers the lives and properties of most people and the safety of engineering facilities. Industrial and civil buildings, military facilities, underground structures, railways, highways, bridges and culverts, farmland water conservancy facilities and hydraulic structures, undersea communications equipment and so on, under the action of strong earthquakes due to the destruction of the ground deformation, abound. Intense earthquakes often greatly exacerbate the disasters caused by earthquakes due to the strong earthquakes on the ground. For example, the main earthquake damage in the 1960 Chilean earthquake (M = 8.5) was caused by landslides and landslides with the largest landslide mass of 30 million cubic meters. In the 1964 Alaska Earthquake in the United States (M = 8.6), the central-southern highways of the peninsula , Bridges and harbor equipment due to land
