Abstract：
To address the uncertainties in construction of drainage gallery by TBM method, the 3 objective functions including construction duration, work cost and work quality have been established by using the critical path method,and the integrated optimization model that takes into account the risks in the 3 objective functions has been created by using the construction organization methods in different construction processes as the decision-making variables.To solve this model, a new lightning search algorithm has been invented by updating the energy of electric discharge body and changing the iteration method of electric discharge body, and the effectiveness of the new algorithm has been verified through simulation of the 3 sets of test functions. The example verification of the model has been conducted by using the excavation of the drainage gallery of Zhejiang Jinyun Pumped Storage Power Station as the example. The integrated optimization model has been solved by using the improved lightning search algorithm, to generate several sets of 3D Pareto optimal solutions that are evenly distributed. The results of optimization prove the rationality of the integrated optimization model for multi-objective construction organization and management and the effec? tiveness of the improved lightning search algorithm, and thus afford the basis for the decision makers to conduct precise and intuitive construction organization and management.
