Concrete gravity revetment and reinforced concrete buttress revetment are both commonly used vertical revetment structures in restricted inland waterways.When the two are used for vertical revetment structure comparison,in addition to the plane layout,structural stability analysis and site construction scheme,the project cost is also an important factor affecting the selection of waterway revetment structure design scheme.To select a more economical vertical revetment,this paper analyzes the influence of natural conditions,use requirements and construction conditions on project cost by combining with engineering cases.The results show that when the main components of cast-in-place concrete such as cement,gravel and sand are rich in sources and low in price,the selection of concrete gravity revetment has the advantage of low cost.When the revetment structure is high,the amount of concrete used is large,and the price of steel is low,the reinforced concrete buttress revetment structure can be given priority.
