%X Current studies on construction security seldom considered relationships and mutual influences between time, cost and other objectives and security. This paper analyzed relationships between duration, cost of completion, guarantee safety cost and safety level of each activity, and deduced safety level index of construction project by the combination of security and system reliability. Then it established a time-cost-safety level equilibrium optimization model through integrating the objective of safety level into time-cost trade-off model. At last, it achieved the Pareto solution of the model using PSO algorithm based on a real example, and demonstrate the effectiveness, rationality and practicality of the model in safety management of construction projects.
