The invention discloses a simulating test platform for an earthquake triggered underwater landslide disaster. The simulating test platform comprises a vibrating table, a water tank and a sedimentationtank, wherein the vibrating table board of the vibrating table is connected with the water tank to form a whole, during vibrating of the table board, the water tank cannot vibrate with vibration of the table board, only a landslide mass model on the vibrating table board vibrates with the vibration of the table board, and damage is caused accordingly. Due to the fact that water cannot transmit shear force, the size of the vibrating table is just required to meet the size of the test model, field and fabrication cost are saved, and influence of water wave turn-back on a test phenomenon and a test result can also be avoided. Besides, water disturbance caused by vibration of water tank walls is difficult to eliminate by a test mode of placing the water tank on the vibrating table, and turned-back water waves can be formed by disturbed water to act on the landslide mass model and result in model damage.
Description
technical field [0001] The invention relates to the field of marine geological engineering, in particular to an earthquake-triggered underwater landslide formation and movement process simulation test platform. Background technique [0002] Submarine landslide is an extremely destructive marine geological disaster, which has the characteristics of fast sliding speed, long sliding distance and strong destructiveness. Earthquake is one of the most important triggering factors, and my country's sea area is in a strong earthquake zone. Under the background of accelerated development of my country's offshore oil and gas resources, the study of earthquake-triggered submarine landslides has become a major strategic demand in the field of national marine engineering safety. In order to ensure the smooth progress of marine engineering and the safety of life and property, it is an important topic to study and prevent submarine landslides triggered by earthquakes. The progress of the ...
