Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0027] like figure 1 As shown, a karst tunnel water inrush early warning system is set in a karst tunnel 1 and includes a karst water pressure acquisition device, a data analysis host 3 and an alarm device; the karst water pressure acquisition device includes at least three penetrating karst bodies 2 and The strain gauge 4 extending into the karst water 5, and the strain gauge 4 is located on the same straight line; the data analysis host includes a controller, and the signal input end of the controller is connected with the signal of the karst water pressure acquisition device and the lithology parameter input module respectively. The output terminal is connected, and the signal output terminal of the controller is connected with the alarm device. The alarm device can be a buzzer, sound and light alarm device, etc., and can be integ...

The invention discloses a karst tunnel water inrush early warning system which comprises a karst water pressure collecting device, a data analysis host and an alarm device. The karst water pressure collecting device comprises at least three stress gauges penetrating a karst body and extending into karst water, and the three stress gauges are located on the same straight line. The data analysis host includes a controller internally provided with a water inrush early warning analysis program for analyzing and judging in real time whether the karst body under the current water pressure is safe according to the input lithological parameters at least including the karst body ultimate stress sigma u and the karst water pressure input in real time; if the karst body is unsafe, a warning command is sent to a warning device; the warning device can send a warning signal after receiving the warning command. A karst tunnel water inrush early warning method is also provided and adopts the karst tunnel water inrush early warning system. The system and method solve the technical problems in the prior art of poor water inrush early warning real-time performance and low accuracy, and can improve the water inrush early warning real-time performance and accuracy.
Description
technical field [0001] The invention relates to the technical field of karst tunnels, in particular to a water inrush early warning system for karst tunnels, and also to a water inrush early warning method. Background technique [0002] Tunnels involve traffic engineering (railways, highway tunnels), water conservancy and hydropower engineering (underground powerhouses, water tunnels) and other fields, and are control projects for national infrastructure construction. After entering the 21st century, a large number of major infrastructure projects such as traffic projects, water conservancy and hydropower projects have been put on the construction agenda, which has greatly promoted the construction of tunnel projects. With the gradual implementation of the national science and technology strategic development plan, the traffic road network spreads all over the western mountainous areas and karst areas with high mountains and karst areas. "Tunnels with prominent characterist...
