A risk-based life cycle design approach for tunnel lining
The purpose of this paper is to develop a framework transforming the traditional tunnel lining design approach into a risk-based life cycle design approach. Firstly, shortages existing in traditional design method are illustrated. Then risk theory and life cycle cost analysis are adopted to deal with these problems such as the high degree of uncertainty and complexity in tunnel lining design. In response to the features of tunnel lining design, the application of life cycle cost analysis, risk assessment and decision-making in tunnel lining design are discussed. And a general design flowchart is presented, which can provide decision makers an informed way to make their choices through evaluating the design options by life cycle cost and risk assessment during its lifetime and obtain an optimum design alternative balanced with safety, durability and cost.
