Safety linkage control method and system for railway under tunnel

Abstract

The invention discloses a safety linkage control method of a tunnel under-passing railway. The method includes: monitoring deformation condition of an existing railway in real time, dividing a whole construction process into a normal state, a forewarning state and a warning state according to the deformation condition of the railway, and continuing construction if the construction is in the normal state; if the construction is in the forewarning state, sending out a warning, and continuing construction after adjusting constructional parameters; if the construction is in the warning state, performing stopping, carrying out feasible suggestions proposed by experts, canceling the warning, and resuming work to control safety implementation of the tunnel under-passing railway. The invention further discloses a system implementing the method, which system comprises a full-automatic monitor module, a construction parameter acquisition module, a data sharing platform and a forewarning platform. Safety hazards occurring in the construction process are solved quickly and efficiently; by using the system, the defect that traditionally a single department independently solves problems is overcome, and inter-department safety awareness is enhanced; tunneling safety and efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of underground engineering and measurement, and relates to a safety linkage control method and system for tunnels passing through railways. Background technique [0002] At present, the railway has become one of the extremely important hub transportation modes connecting cities in China. Once an accident occurs, the consequences will be disastrous. At the same time, the subway is playing an increasingly important role in people's daily life due to its large transportation capacity and fast speed. It is irreplaceable for alleviating the pressure on ground traffic. The existing railway situation. [0003] The construction of the new tunnel will disturb the surrounding soil, cause the displacement of the soil layer, and the deformation will be transmitted upward to the track structure, causing the track to be uneven and affecting the safe operation of the railway. In the past, certain theoretical calculation ...

AI Technical Summary

Problems solved by technology

In the actual construction process of new tunnels, it is impossible to conduct a completely accurate analysis of the working conditions and loading conditions of the railway foundation, and the initial physical and mechanical properties of rock and soil materials and after being disturbed by construction have great uncertainty and variability. , making it impossible to accurately predict the safety of high-speed railways using the original theoretical calculation model
