The stress and stability analysis of arch dam and abutment are the main task of traditional arch dam design. Nowadays there are two kinds of analysis method to use. One method is the arch-cantilever load-distribution method, in which the arch dam stress and abutment thrust are calculated, while the stability of abutment is evaluated by rigid body method or other method. The other is FEM method, which evaluates the arch dam stress and stability of abutment at the same time.

Combined with the idea of \\\"grading district\\\" in Managing the Information of Exurb Safety and \\\"liability tied\\\" and taking into account of factors affecting exurb road safety, this paper analyzes in depth the basic functions and system design of safety management information system for Exurb Road. The system gets the functions such as management with different levels of exurb safety information, safety analysis, safety forecast and safety assessment. Furthermore, the system defines the responsibilities and duties related to the managers of exurb road safety and establishes an incentive mechanism for their assessment.
