The invention discloses a seabed safety management method and a seabed safety management system for a sea area section subsea tunnel. A submarine tunnel numerical simulation model is established according to surrounding rock physical and mechanical parameters of a submarine tunnel in a sea area section so as to determine plastic vault settlement, water inrush seabed settlement and water inrush vault settlement. The original vault settlement according to the vault surrounding rock whole-process deformation curve and the distance between the section and the excavation surface during monitoring implementation is determined. Finally, the seabed safety management is performed on the subsea tunnel according to the actually measured surrounding rock deformation, the plastic vault settlement, thewater inrush seabed settlement, the water inrush vault settlement and the original vault settlement. According to the method, the subsea tunnel water inrush process is subjected to stage division; based on the quantitative relation between the seabed safety and the tunnel surrounding rock deformation, the seabed safety of the subsea tunnel can be managed according to the actually measured surrounding rock deformation, the subjectivity of subsea tunnel surrounding rock stability control is reduced, the construction safety is ensured, and casualties and economic losses caused by water inrush accidents in construction are avoided.
Description
technical field [0001] The invention relates to the field of subsea tunnels, in particular to a seabed safety management method and system for subsea tunnels in sea areas. Background technique [0002] Submarine tunnels are buried under seawater, and the safety status of the seabed cannot be directly observed. The data that can be measured during the project are usually the deformation and stress of the surrounding rock of the tunnel. How to manage the safety of the seabed based on the measured data on site is a major challenge during construction. major problem. Most of the existing seabed safety management methods for subsea tunnels follow the relevant engineering experience of mountain tunnels, and are not implemented in combination with the characteristics of subsea tunnel engineering. There is a lack of scientific basis, and the processing results often have large uncertainties. The results obtained are often different from the actual situation. There is a large gap, w...
