The invention discloses a tunnel
supporting system based on a multi-cavity composite duct piece structure and intelligent monitoring and evaluation, and the tunnel
supporting system comprises an
assembly type multi-cavity duct piece structure, a multi-directional self-locking type buckle connection
assembly, a multi-mode intelligent
evaluation system and an active early warning subsystem, the
assembly type multi-cavity
segment structure is formed by splicing a plurality of multi-cavity segments, and the interior of the assembly type multi-cavity
segment structure is divided into a plurality of cavities through longitudinal and transverse partition plates. The multi-
modal intelligent
evaluation system integrates a CNN model, an LSTM model, an XGBoost model and a model fusion scoring module to
score the stability of the tunnel
support system; the active early warning subsystem comprises multiple types of intelligent sensors, an
edge computing node and a cloud reasoning module. The
system is matched with a flexible self-locking connection technology, an intelligent supporting stability
analysis method fusing multi-model dynamic evaluation is adopted, active early warning linkage is achieved through real-time edge data collection and a multi-stage judgment mechanism, and the stability, intelligence and reliability of a tunnel supporting structure are remarkably improved.
