Submarine landslide and debris flow small simulation water tank and test method

Abstract

The invention discloses a submarine landslide and debris flow small simulation water tank and a test method. The bottom of a water tank is provided with guide rails, the bottom of the water tank is provided with horizontal adjusting truckles, the horizontal adjusting truckles are in brake states after the water tank is in place, the guide rails are provided with cushion blocks at intervals, a plurality of modular base plates are arranged on the cushion blocks, the cushion blocks are arranged from low to high to enable the plurality of modular base plates to be connected to form a landform withan inclination angle, the bottom of one end of the lower position of the landform, close to the water tank, is provided with a drain hole, a separating block with a filtering screen is arranged between the drain hole and the guide rails, the modular base plates comprise a flat straight base plate with a rectangular hole at one side, a flat straight base plate, a base plate with a convex structure, and a flat straight plate with a groove connected in sequence, a water-inlet pipe is arranged at the rectangular hole of the flat straight base plate with the rectangular hole, a triggering box is arranged on the flat straight base plate with the groove, and the triggering box is provided with a pulling door. The beneficial effects are that the test consumption is reduced, and the test efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of marine engineering geology, and relates to a small simulated water tank for submarine landslide and debris flow and a test method. Background technique [0002] The sliding of submarine landslides and the resulting submarine debris flow can cause impact damage to submarine pipelines, electric / optical cables, submarine wellheads and other facilities. Carrying out research on the dynamic characteristics and movement laws of submarine landslides / debris flows in seawater environments is the basic work for evaluating and predicting the impact speed and impact range of such geological disasters. Carrying out flume test is a common and important means to study submarine landslide and debris flow movement. When using conventional general-purpose large-scale water tanks to carry out tests, the modification process is complicated and difficult to operate. A single test consumes a large amount of model soil, water,...
