Research on Risk Transfer Route of Underground Cavern Group Construction Schedule Based on ISM-SD
In view of the transfer phenomenon of construction schedule risk in underground cavern group of hydro-power project,a risk transfer route analysis method for underground cavern group construction schedule based on Inter-pretative Structural Modelling Method(ISM)and System Dynamics(SD)is proposed.According to the construction characteristics of underground cavern group,the construction schedule risk index system of underground cavern group was established.Combined with the risk transfer mechanism,the transfer relationship among factors was analyzed by u-sing ISM,and the risk factor transfer matrix was established.Then the risk factor relation comparison table was summa-rized.The transfer path between risk factors was analyzed through SD,and the risk transfer path network of construction schedule was revealed.The integrated ISM-SD was applied to construct a risk transfer route analysis model of under-ground cavern group construction schedule.Finally,a large-scale hydropower station underground cavern group project in southwest China was analyzed by the method.The results show that this method can identify the important factors and key transfer routes of construction schedule risk,which provides decision-making basis for the risk management of under-ground cavern group construction schedule.
