[0055] An experimental method for simulating a projectile landslide experimental device, the steps of using the pneumatic projectile power system experimental method are as follows:

[0056] Step 1: Fabrication of the simulated structural surface 13: The simulated structural surface 13 is the fault layer located in the projected part and the projected soil, which has a certain degree of air tightness and connectivity. Analyze the composition of the original structural surface and the surface morphology of the structural surface, make the natural structural surface of the rock, and place some magnetic fillers 16 in the simulated structural surface 13 to simulate the bonding material in the structural surface in reality; Hours, the bonding force between the structural surfaces can also be adjusted, which can also replace rainfall and freezing, and change the c and φ values ​​in the slip belt by adjusting the current size to simulate the c and φ values ​​​​under real rainfall and ...

Abstract

The invention discloses a simulated projectile landslide experimental device and method. The experimental device adopts a pneumatic projectile power system including a vibration device. A simulated structural surface is arranged at the top of the vibration device; a side slope soil body is arranged at the simulated structural surface; and the inside of the side slope soil body is connected with anitrogen bottle through a ventilation pipe. A simulated rainfall device is arranged at the top of the simulated structural surface. A high-strength fiber ventilating layer, an acceleration sensor, a displacement sensor and a stress sensor are arranged between the simulated structural surface and the side slope soil body. The inside of the simulated structural surface is filled with a magnetic filler; and an electromagnet is arranged inside the side slope soil body and cooperates with a flexible iron piece disposed in a projectile soil body to generate an electromagnetic force. After simulationof the motion process of the projectile soil body under the air pressure effect and the motion process of the projectile soil body under vibration, the energy losses are analyzed and thus the real principle of causing the earthquake and projectile landslide is disclosed.

Description

technical field [0001] The invention relates to the technical field of earthquake disaster simulation and prevention, and is mainly used for simulating a projectile landslide caused by an earthquake, and studying its generation principle and corresponding preventive measures. Background technique [0002] At 2:28 pm on May 12, 2008, a huge and catastrophic magnitude 8 earthquake (Wenchuan Earthquake) suddenly occurred in the middle and north section of Longmen Mountain in Sichuan, my country. The 5•12 Wenchuan earthquake was the most destructive earthquake since the founding of the People's Republic of China, and it was also the earthquake with the most serious casualties after the Tangshan earthquake. The severely damaged area exceeded 100,000 square kilometers. Among them, there were 10 counties (cities) in the extremely severe disaster area, 41 counties (cities) in the relatively severe disaster area, and 186 counties (cities) in the general disaster area. As of September...
