Study on Scenario Analysis Method Based Safety Pre-Warming of Large Construction Engineering

For large construction engineering, to perform safety pre-warming more efficiently, scenario analysis method (SAM) is studied for safety pre-warming of large construction engineering (SPLCE). Implement flow framework of SAM is established, the key cycles of SAM are discussed. To validate the validity of SAM for SPLCE, some practical instances of SPLCE are abstracted so as to generated application and testing sample. Comparing with whole index evaluating method (WIEM), under the condition of considering only limited key driven forces and some normal indexes, the result by SAM are almost the same with that by WIEM. SAM improves the efficiency of SPLCE, and it is fit for solving complex predicting, analyzing and evaluating problems such as SPLCE.
