Embodiment 1

[0043] see Figure 1-3 , an experimental device for simulating the process of soil cracking and collapsing under the action of periodic water level rise and fall, which includes a water level rise and fall simulation system for simulating the water level rise and fall during the experiment; the internal support of the water level rise and fall simulation system is equipped with The support system for installation; the support system is equipped with a measurement system for measuring and recording the experimental process. By adopting the above-mentioned experimental device, it can be used to study the failure process of the soil cracking and collapsing process under the action of the periodic rise and fall of the water level.

[0044]Further, the water level rise and fall simulation system includes a bottom plate support 1, and transparent baffles 2 are fixedly installed on the top four sides of the bottom plate support 1 and surround the entire water tank structure; the uppe...

Embodiment 2

[0050] The experimental method of using the experimental device to simulate the process of soil cracking and collapsing under the action of the periodic rise and fall of the water level comprises the following steps:

[0051] Step 1. After the overall assembly of the water level lifting simulation system is completed, check whether the lifting rod 5 is in normal use and fix its position. After assembling the heating fan 12, the camera 13 and the support rod 6, place them on the transparent baffle 2;

[0052] Step 2: After assembling the sample box 11, the connecting rod 10, the electronic balance 9, the connecting plate 8 and the bearing plate 7, place it in the air above the lifting rod 5. At this time, the height of the lifting rod 5 is the lowest, and the sample box 11 is not in contact with the bottom plate of the bottom plate support 1;

[0053] Step 3, open the water inlet valve 3, raise the water level in the water level lifting simulation system to a preset height and ...

Abstract

The invention provides an experimental device for simulating the cracking and collapsing process of a soil body under the action of periodic water level rising and falling. The experimental device comprises a water level rising and falling simulation system for simulating the water level rising and falling change in the experimental process; a supporting system used for installing the experiment device is installed in the water level rising and falling simulation system in a supporting mode. A measuring system used for measuring and recording the experiment process is installed on the supporting system in a matched mode. The problem of lack of simulation equipment in the gradual collapse process of the soil body caused by periodic rise and fall of the current measured water level can be solved, real-time data of mass change of soil particles and water in soil in the cracking and collapse process of the soil body can be accurately mastered, the device is simple in structure, and the use method is convenient and rapid.

Description

technical field [0001] The invention relates to the fields of water conservancy and rock-soil experiments, in particular to an experimental device and method for simulating the cracking and collapse process of soil under the action of periodic rise and fall of water level. Background technique [0002] There are nearly 100,000 reservoirs and lakes of various types in my country, and nearly 50,000 rivers. Changes in the water levels of lakes and reservoirs have caused countless geological disasters. The periodic rise and fall of the water level of the reservoir or river causes the bank slope soil to experience repeated dry-wet cycles, causing the soil to crack and disintegrate until it collapses. It is the main inducing factor of various geological disasters. , water conservancy engineering, traffic engineering and other disciplines of important research topics. The current simulation experiment devices and methods mainly have three deficiencies: [0003] (1) The water evap...
