哥斯达黎加地震的结构震害状况该地震于1992年4月22日发生在哥斯达黎加人烟稀少的地区,震级7.4级。地震使地貌发生了剧烈的变化,包括震中区山地大面积滑坡、东海岸沿线隆起达1.5m,但结构破坏相对说还算比较轻。不过,利蒙港及其附近的许多仓库和钢筋混凝土建筑倒塌或严重破坏,相当多的高木桩支承房屋被损坏。最值得注意的是,主要由于地基产生液化和路堤软土层的过最位移,使许多现代公路桥梁遭到了破坏。
Structural earthquake damage situation in the Costa Rican earthquake The earthquake occurred on April 22, 1992 in Costa Rica’s sparsely populated area, with a magnitude of 7.4. The earthquake caused dramatic changes in the landscape, including a large area of landslides in the epicentral area and uplift of 1.5m along the east coast. However, structural damage is relatively light. However, many warehouses and reinforced concrete buildings in and around Limon port have collapsed or been severely damaged, and a considerable number of high stakes supporting houses have been damaged. Most notably, many modern highway bridges have been damaged due to the liquefaction of foundations and the over-displacement of embankment soft soil layers.
