Abstract
Safety alarm method is the key to the deformation of deep excavation engineering control security technology. A new safety alarm system was put forward by the deformation behaviors of soil-rock mass because that the alarm value of control in the code was too preliminary, which could not effectively reflect the deformation state of deep excavation engineering. The new safety alarm method involved three kinds control indicators: the accumulative value, monitoring rate and monitoring acceleration; and four levels of alarm: blue alarm, yellow alarm, orange alarm and red alarm. Alarm levels and the safety control key indicators were corresponded to the tasks and responsibilities. The one excavation example was verified for the practical application of the alarm system.
