Method of testing influence of leakage water on in-service tunnel operation safety and system thereof

The invention provides a method of testing an influence of leakage water on in-service tunnel operation safety and a system thereof. The method comprises the following steps of a, constructing tunnel virtual environment under different water seepage conditions and making a driver carry out simulation driving in the virtual environment; b, collecting behavior information of the driver and carrying out statistics on a water seepage position and a water seepage amount in the tunnel virtual environment; c, according to the behavior information of the driver, the water seepage position and the water seepage amount in the tunnel virtual environment, determining a vehicle driving safety grade under the water seepage condition in the tunnel. By using the method and the system of the invention, a direct test does not need to be performed on a seepage disease in the tunnel which is actually operated; an operation tunnel leakage water grading and vehicle driving safety influence assessment efficiency are increased; influences of different water seepage amounts on tunnel operation functionality and safety can be quantitatively tested in a virtual operation tunnel scene; the high-efficiency and energy-saving new method is provided for operation tunnel leakage water grading evaluation; manpower and material resources are greatly reduced and accuracy of the test is increased.
