Model test device and test method for monitoring effect of tunnel water inrush on groundwater environment

Abstract

The invention discloses a model test device and a test method for monitoring an effect of tunnel water inrush on groundwater environment. The device comprises a whole model frame of a groundwater test, wherein a groundwater channel model is arranged in the whole model frame of the groundwater test, an inlet end of the groundwater channel model is connected with a water tank mounted at the top of the whole model frame, and an outlet end is connected with a tunnel model; a layer of fine stone is paved on the upper surface of the groundwater channel model; a groundwater level monitoring device is placed on a frame of the tunnel model; a CT(captive test) detection device which is vertical to a groundwater channel is arranged in the whole model frame of the groundwater test, the whole model frame of the groundwater test is made of antiseptic wood materials, besides two layers of insulated paint are brushed on the inner side of the whole model frame, and the whole model frame is coated with waterproof cloth to form a leakproof combination; a flume used for storing excurrent groundwater caused by the water inrush is placed outside the opening of a tunnel, and the groundwater is drawn back to the water tank through a water pump to be recycled.

Description

technical field [0001] The invention relates to a groundwater environment monitoring model test device, in particular to a model device for monitoring the impact of tunnel water inrush on the groundwater environment by means of a resistivity CT method, and belongs to the technical field of model tests. Background technique [0002] In recent years, more and more tunnel projects have been built in the fields of transportation, hydropower and other fields, and the geological conditions are becoming more and more complex. During the excavation and construction of tunnels, unforeseen engineering geological disasters are prone to occur, such as water inrush, mud inrush, collapse etc. my country is one of the countries with the most serious water inrush disasters in tunnels and other underground projects. Water and mud inrush disasters will not only cause casualties and economic losses in various tunnels and other underground projects, but also cause serious environmental damage. ...

Problems solved by technology

The actual engineering monitoring is undoubtedly the most objective and direct research method, but because the location and scale of the water-bearing structure are not known in advance, and it is easily interfered by the multiple solutions of the a
