Optimization of Horizontal Terrace Ridge Section in Land Consolidation Engineering

In order to study optimization of horizontal terrace ridge section design in land consolidation engineering，influence of different ridge heights and outer slope angles on the land occupation ratio of ridge and cut-fill volumes was analyzed.On this basis，taking land occupation ratio of ridge and cut-fill volumes as evaluation indexes，comprehensive evaluation of ridge section design scheme was preliminary discussed.Results showed that when ridge was higher and outer slope was steeper，land occupation ratio of ridge was smaller，effective tillage area was larger.When ridge was lower and outer slope was slower，cut-fill volumes was smaller，project cost was smaller.Land occupation ratio of ridge and cut-fill volumes was mutually exclusive.Therefore，in the process of horizontal terrace ridge section design in land consolidation engineering，weights of each evaluation index should be determined rationally according to local conditions，so as to determine optimal design scheme of ridge section design.
