由于地震造成煤气、输油、供水管道等埋置生命线严重破坏。生命线对人们的健康,给养和安全是十分重要的,所以生命线地震工程目前已引起工程界的重视。地震对埋置生命线破坏的原因有滑坡、构造隆起、下沉、砂土液化、断层错位和地面振动(波传播效应)。就性质来说滑坡、构造隆起和土壤液化破坏面积 As the earthquake caused by gas, oil, water pipelines and other buried lifeline serious damage. Lifeline for people’s health, provision and security is very important, so lifeline seismic engineering has now attracted the attention of the engineering community. The causes of the destruction of buried lifeline by earthquake include landslide, tectonic uplift, subsidence, sand liquefaction, fault dislocation and ground vibration (wave propagation effect). Landslides, tectonic uplift and soil liquefaction destroy areas by their nature
