Abstract

The invention discloses a method for establishing a pulse seismic oscillation response model taking a mountain terrain effect into consideration. A near-fault area tends to generate strong pulse seismic oscillation, and the mountain terrain can cause obvious amplification effect on pulse earthquake. According to the method, by comparing the acceleration spectrums of a trapezoid mountain model anda free field model under the action of pulse seismic oscillation, the obvious amplification effect of mountain terrains on pulse seismic oscillation is verified. Therefore, when the mountainous area is subjected to near-fault region earthquake risk evaluation, the amplification effect of mountain terrain on pulse seismic oscillation needs to be considered, so that pre-seismic disaster prevention and evaluation, earthquake-time emergency response and post-earthquake reconstruction planning can be realized in a manner of being closer to the actual situations.

Description

technical field [0001] The invention relates to the technical field of mountain terrain effects, in particular to a method for establishing a pulse ground motion response model considering mountain terrain effects. Background technique [0002] Large-scale earthquake disasters will induce thousands of landslides, which cause huge loss of life and property to human beings, and even the losses caused by landslides account for more than half of the entire earthquake loss. In my country, earthquake landslides are a common secondary disaster in earthquake disasters, and are also a common type of disaster in seismic activities. They not only occur on a large scale, but also pose a huge threat to human life. In addition, earthquake landslides are highly random, It is difficult to prevent and control, and it often brings great damage to buildings and traffic lines in mountainous areas, endangering the safety of life and property in the affected area. It is a type of geological disast...
