Embodiment Construction
[0030] Specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.
[0031] Such as figure 1 As shown, the diagnostic analysis system for implementing the diagnostic analysis method includes a single-chip microcomputer, a first camera 3 and a second camera 4 respectively installed on both sides of the tunnel 1 facing the fault plane 2, and installed on both sides of the tunnel 1 facing the fault plane 2. several humidity sensors;
[0032] The first video camera 3, the second video camera 4 and the ...

The invention discloses a fault-crossing tunnel disease diagnosis and analysis method which comprises the following steps: acquiring current time, when time requests are fulfilled, a second camera acquires a first image and judges whether the first camera positions in the first image and the reference image are at the same position or not; if yes, the second camera is started to collect a second image for slab staggering judgment, and when slab staggering exists and the width of slab staggering is larger than a certain value, the collected first image, the collected second image and information that serious slab staggering occurs at the fault of the tunnel are compressed and then sent to a road maintenance department; when the slab staggering exists and the width of the slab staggering issmaller than a certain value, judging whether a humidity sensor with a set proportion continuously uploads humidity information between the first images acquired by the second camera twice or not; andif so, crack detection is carried out on the second image, and the acquired first image, second image and crack detection result and hazard information of slab staggering and water seepage of the tunnel at the fault are compressed and then sent to a road maintenance department.
Description
technical field [0001] The invention relates to the field of geological disaster monitoring, in particular to a method for diagnosing and analyzing tunnel diseases across faults. Background technique [0002] Faults are widely developed structural forms in tectonic movements. It varies in size and scale, ranging from less than one meter to hundreds or thousands of meters. But they all destroy the continuity and integrity of the rock formation. On the fault zone, the rocks are often broken and easily eroded by weathering. Valleys are often developed along the fault line, and sometimes springs or lakes appear. [0003] As my country's efforts to build the Great Southwest continue to increase, in the construction of major projects such as high-speed railways, expressways, and diversion tunnels, especially long tunnels, it is inevitable to cross multiple fault zones. For example, the Dengjiaping Tunnel is 10km long and passes through 9 fault zones; the Nibashan Tunnel of the...
