A test device and test method for simulating submarine landslide impact structure

Abstract

The invention relates to a test device and test method for simulating the impact structure of a submarine landslide, which is mainly used for the research of the impact and damage effect on the structure after the submarine landslide is destabilized and destroyed, including a frame system, a lifting system, and an earth bin The four parts of the system and the test system provide support protection and test space for the whole device through the frame system, adjust the angle of the slideway within a certain range through the lifting system, and realize the stable storage and quick release of simulated landslide materials through the soil storage system. The test system realizes the dynamic monitoring of the distribution law and change process of the structural strain during the landslide impact process. The invention fully restores the rapid start of the submarine landslide and the actual damage phenomenon of water slide migration, fully considers the influence of the distance between the structure and the submarine landslide on the impact effect, and realizes a submarine landslide impact structure with an adjustable distance The advanced physical model test device avoids the shortage of theoretical calculation and numerical simulation.

Description

technical field [0001] The invention relates to the technical field of civil engineering tests, in particular to a test device and a test method for simulating the impact of submarine landslides on structures, and is mainly used for studying the impact characteristics and damage effects on marine engineering structures after submarine landslides are destabilized and destroyed. Background technique [0002] Submarine landslides are a major form of marine geological disasters. Submarine landslides directly affect the construction and operation of drilling platforms, submarine optical cables, wind power pile foundations, and port terminals. Frequent or sudden submarine landslide geological disasters in offshore areas have seriously affected the construction of offshore economic belts and restricted the development of my country's Maritime Silk Road. Advance in an all-round way. Submarine landslides have special occurrence environments, complex genetic mechanisms, and unique fai...

AI Technical Summary

Problems solved by technology

Due to the late start of research on submarine landslides, few means, and great difficulty, the current research on the impact of submarine landslides on engineering structures has seriously lagged behind the construction practice of marine engineering.

[0003] In recent years, some scholars have used theoretical calculation and numerical simulation methods to study the impact of submarine landslides on engineering structures, but they are limited by many assumptions, resulting in the degree of matching between their research results and engineering reality. lower

The physical model test is the most intuitive and reliable means to carry out the research on submarine landslide impact engineering structures at this stage, but there is no mature test device for submarine landslide impact structures available
