High-speed landslide starting mechanism tester

Abstract

The invention discloses a high-speed landslide starting mechanism tester comprising a sliding table (1) and a platform (2), wherein the sliding table is connected with the platform through a rotating shaft (3); the sliding table is supported on a lifting mechanism capable of adjusting the included angle between the sliding table and the platform; a loading jack (4) is arranged on the sliding table, and the jack (4) forms a loading and transferring mechanism with a force transferring plate (6) through a stress ring (5); a rainfall simulating device is arranged above the tester; and timely sensors used for monitoring the motion features of a tested sliding object are arranged on the sliding table and the platform. In a landslide monitoring test, an anchoring segment is conveniently arranged between the sliding object and a sliding bed and is used for monitoring the motion features of the sliding object and the vibration signal features of the sliding table and the platform at the shearing moment and in the operation process of a landslide locking segment so as to analyze and research a landslide starting mechanism.

Description

Technical field [0001] The invention mainly relates to the field of testing machines, in particular to a high-speed landslide departure mechanism testing device. Background technique [0002] High-speed and long-distance landslides occur suddenly, with large volume, fast sliding speed and long sliding distance, often causing greater loss of life and property. And with the occurrence of frequent earthquakes and extreme weather, the frequency of such landslides is increasing. Although domestic and foreign scholars have conducted extensive research on this type of landslide since the Vaiont landslide in Italy in 1963, the mechanism of high-speed and long-distance landslides is still a worldwide problem. Carrying out systematic experimental research on this type of landslide, and obtaining its occurrence mechanism and occurrence phenomenon, has great practical significance for the prediction and prevention of this type of landslide, and can reduce the disaster caused by this ty...

AI Technical Summary

Problems solved by technology

[0004] 1. It is considered that the high speed of landslide departure mainly comes from the conversion of potential energy to kinetic energy, and less consideration is given to the effect of ground stress

[0005] 2. In the study of elastic energy release, only the conversion result of energy is considered, but there is a lack of research on the conversion process, such as the impact of the vibration caused by this conversion on the occurrence of landslides

[0006] 3. There are few systematic experimental studies, and most of them are phenomenon analysis and assumptions of landslide cases

[0007] 4. A small number of tests are mostly aimed at the remote mechanism after the start of the landslide, such as high-speed collision test, wind tunnel test, and there are few experimental studies on the start-up mechanism of the landslide

[0008] The main reason is the lack of corresponding test methods and test equipment, it is difficult to reproduce the start-up process of high-speed remote landslides, and the corresponding test indicators and test methods
