基于施工造价分析的防波堤结构方案比选

斜坡堤和直立堤作为常见的防波堤结构形式,当两者用于设计方案比选时,工程造价是结构选型须考虑的重要因素。通过结合实际工程案例,分析自然条件、主材供应、施工难易、工期要求等方面对工程造价的影响。结果表明,当水深较浅、石料来源丰富的情况下,斜坡堤具有造价较低的优势;对于水深较大、有特殊景观使用要求的情况下,可考虑选用直立堤。

Comparison and selection of breakwater structure scheme based on analysis of construction cost

Rubble mound breakwater and vertical breakwater are the common forms for breakwater structures,and the cost of the project is the important factor to be considered in the structure selection when the two structures are used for comparison and selection in the design scheme. This paper combines with an actual engineering case,analyzes the impact on the project cost based on natural conditions,main material supply,construction difficulty degree,and construction period requirements. The results show that when the water depth is shallow and the stone source is abundant,the rubble mound breakwater has the advantage of lower construction cost. For the large water depth and special landscape requirements,vertical breakwater can be selected.
