Embodiment

[0052] Such as figure 1 As shown, this embodiment takes the Hongdoushan Tunnel as an example to carry out the test experiment. The Hongdoushan Tunnel is a control project for the entire line of the newly-built Dalin Railway Line. It belongs to the high and middle mountain erosion and denudation landform, with large terrain undulations, Hongdou Mountain is distributed in the northeast direction, and the valleys are developed. Overlying Quaternary new artificial filling soil, slope colluvial gravel soil, slope residual gravel soil; underlying Triassic metamorphic sandstone, slate, schist, Indosinian biotite granite, etc. The Lancang River fault and the Nanting River fault hold different weathering areas. The geological structure in the area is complex, with many folds, active faults and deep and large faults. broken. The surface water in the area is mainly seasonal mountain streams, and the flow rate varies greatly with seasons. The groundwater is mainly bedrock fissure water...

Abstract

The invention discloses a TSP-based comprehensive advance forecast method for harmful gases in tunnels, which comprises the following steps: S1: detecting the rock mass in the tunnel, and recording the integrity of the rock mass in the tunnel; S2: according to the obtained completeness of the rock mass in the tunnel, Geological sketch; S3: Collect data for geological prediction of tunnel seismic wave method, and obtain the collected data; S4: Detect harmful gases in the rock mass, and obtain harmful gas detection results; S5: According to the data collected in S3 Harmful gas forecasting is carried out based on the harmful gas detection results in S4, and the forecast results are obtained; S6: according to the forecast results in S5, harmful gas protection is carried out; through the intervention of TSP technology, the accuracy of harmful gas prediction for non-coal-measure tunnels is effectively enhanced Degree, can more effectively complete the prediction of harmful gases.

Description

technical field [0001] The invention relates to the field of tunnel harmful gas prediction, in particular to a TSP-based comprehensive advance prediction method for tunnel harmful gas. Background technique [0002] Since the beginning of the 21st century, my country's economic level, comprehensive national strength, and technological level have shown a rapid and stable trend of continuous improvement. National policies and people's needs have continued to increase. In order to seek a greater development environment, the number and scale of underground projects are increasing day by day. The development of mountain traffic cannot do without the development of tunnel engineering. With the increase of the number of tunnels, the geological problems and geological disasters encountered by the tunnels have become diversified, complicated, and difficult to prevent and control. Among them, there are more and more toxic and harmful gas accidents in non-coal-measure tunnels. Not only...
