The structural design of a combined regulating pool for a new waterworks in South China was taken as an example.For building a plant on complex hilly terrain,the slope support structure scheme,which considering the influencing factors and design principles were presented.In the pool structure analysis under multiple conditions,the key points were extracted,and the difference between three-dimensional finite element analysis calculation method and single component simplified calculation method was compared.In the compo-nent layout,an optimized structure suitable for large-span pool structures was proposed.This study introduces the key points and analysis of structural design of multi-condition combined pool in complex geologic environ-ment,which takes the safety,feasibility,rationality and economy into account.And the results could provide a certain reference for the following similar pool structure design of water supply and sewerage engineering.
