Abstract

The invention discloses a device for simulating the rupture of a thrust fault, comprising: a loading device, a supporting device, a testing device, an auxiliary device and a fault model device; the research on the pulsation of a fault rupture is carried out by means of a physical model experiment, and reveals different types of seismogenic faults and The characteristics and spatial distribution of pulsed ground motions generated by different fault parameters are used to establish a characteristic model of pulsed ground motions based on the type of seismogenic fault; The records of pulse-type earthquakes are not enough, and the characteristics of near-fault pulse-type earthquakes cannot be accurately obtained in a statistical sense. This device can be used to study the pulses generated by different parts of the fault when the thrust fault ruptures, and record the fault when the fault ruptures. Pulse characteristics and distribution rules.

Description

technical field [0001] The invention relates to the technical field of geological sciences, in particular to a device for simulating thrust fault rupture. Background technique [0002] The rupture mechanism of seismic faults has a great influence on the generation of pulse ground motions and their intensity parameters. With the development of science and technology, more and more pulse ground motions have been recorded, and the research on its damage to engineering structures has become more and more in-depth. In the Northridge earthquake in 1994, the Kobe earthquake in 1995, and the earthquake in 1999, a large number of studies have shown that under the same seismic moment magnitude and site conditions, compared with far-field earthquakes, near-field pulse-type earthquakes have more impact on engineering structures. Great destructive power. In general, pulse ground motions are caused by the forefield directional effect and slide effect in seismic fault rupture. The veloc...
