Problems solved by technology

However, due to the influence of sample size, test conditions and test simplification, there are not small differences between the indoor test and the actual site.
On-site monitoring is often affected by equipment burial, equipment stability, and human factors, which is uneconomical, time-consuming and laborious

Embodiment Construction

[0042] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0043] 1. The overall structure of the test tank

[0044] As mentioned above, the overall structure of the test tank is shown in Figure 1.

[0045] 2. The structure and function of each component (as shown in Figure 1, 2, 3)

[0046] 1. Container(1)

[0047] As shown in Figure 1, the container (1) is a rectangular container made of high-strength glass fiber reinforced plastic or other high-strength transparent materials, on which horizontal and vertical scales are arranged, through which the changes in the shape displacement of the soil to be tested can be observed and monitored. .

[0048] 2. Brackets (2)

[0049] The bracket (2) is a square frame, which is connected by angle steel or other high-strength materials, and is provided with mounting holes for the installation of the rainfall sprinkler (5) and other auxiliary test equipment (such as cameras, data acquisition instruments) ...

Abstract

The present invention discloses a rock model test flume and method based on test circumstance and variable interface, and equipment thereof. The structure of the test flume is: water inlet and outlet are set on the bottom of test container fixed and supported by bracket, combinable roughness plate is set in the test container and angle protractor and vertical line are on the side wall of test container; mounting hole is set on the top of the bracket to mount raining nozzle or other assistant apparatus; tank, water pump, conduit pipe and raining nozzle are jointed in turn outside the test container. The present invention can simulate model test of geotechnical body raining or inundating under the difference conditions of geotechnical interface or interface friction, also can test at one condition and fit for model test of other medium under the conditions of difference interface or raining and inundating also.

Description

technical field [0001] The invention relates to a rock-soil model test equipment, in particular to a rock-soil model test tank and a test method based on variable test environment and contact surface. Specifically, this technology can simulate model tests of rock and soil under rainfall or flooding conditions and model tests under different rock-soil contact surface conditions, and is also applicable to model tests of other media under rain or flooding conditions. Background technique [0002] The failure of slopes under rainfall and flooding conditions has always been an important subject in geotechnical engineering research. For many years, laboratory tests of rock and soil mechanical properties have been generally used to obtain strength parameters for stability analysis and on-site monitoring. However, due to the influence of sample size, test conditions and test simplification, the indoor test is quite different from the actual site. On-site monitoring is often affecte...
