Optimization Design of Surge Chamber for TNH Hydropower Project in Nepal
The TNH Hydropower Station is one of the typical infrastructure projects under the Belt and Road Initiative between the Nepalese government and the Chinese government.In detail design,through analysis on the drawings related to surge chamber,the layout of surge chamber was optimized.And the hydraulic review and stability analysis calculation results verified the rationality of the optimization design parameters.Because of the optimization design,the difficulty of roof arch construction was reduced and the project costs were saved.Under the strict requirements of consulting engineers,after the modification of the third version of the drawings,the final optimization design results were recognized by the engineers,and the layout drawings of surge chamber was approved,which laid a solid foundation for the subsequent drawings such as excavation sup-port and lining structural drawings.
