Abstract
Yuwa Hydropower Station is one of the projects adopting the EPC contract mode type in PowerChina Chengdu Engineering Corporation Limited.The project estimated investment of Yuwa Hydropower Project is much higher in the feasibility study stage.After optimization of technical proposals was done for many times,the project was successfully in construction on time.In order to control the project cost,combined with the risk analysis of uncertainty in underground engineering,the optimization of design parameters of excavation and concrete lining for long headrace tunnel is one of the fine design methods of hydropower station.This paper in-troduces the reinforcement calculation of concrete lining design for headrace tunnel with the structural mechan-ics and finite element method.Though comparative analysis,optimizing reinforcement quantity and reducing project investment are achieved.This paper summarizes some experience of optimizing the lining structure in headrace tunnel,which can be used as reference for other similar projects.关键词
