摘　　要：铺面联锁块已在我国水运工程道路堆场得到广泛应用。联锁块形状是异形的,具有双向联锁作用,其抗压强度是JTS 257-2008《水运工程质量检验标准》中要求的必检指标。GB/T 28635-2012《混凝土路面砖》及GB 32987-2016《混凝土路面砖性能试验方法》中抗压强度试验方法没有规定异形块体承压面积的测定方法,不能满足联锁块抗压强度试验检测的需要。为此,通过分析国内外相关标准,结合工程实际所采用的试验方法及检测经验,提出了具有水运工程特点的联锁块抗压强度试验检测方法,以正确评价联锁块抗压强度,保证联锁块铺面工程的安全性,促进水运工程道路堆场的高质量发展。Pavement interlocking blocks has been widely used in the road and storage yard of water transport engineering in China. The shape of interlocking block is special-shaped and has two-way interlocking function, and its compressive strength is a necessary inspection index required in JTS 257—2008 Standard for quality inspection of port waterway engineering construction.GB/T 28635—2012 Precast concrete paving units and GB 32987—2016 The method for performance of concrete paving units do not specify the method for measuring the compressive area of special-shaped blocks, which cannot meet the compressive strength test of interlocking blocks. For this reason, by analyzing the relevant standards at home and abroad, combined with the actual test methods and testing experience used in the project, a test method for the compressive strength of the interlocking block with the characteristics of water transportation engineering is proposed to correctly evaluate the compressive strength of the interlocking block, ensure the safety of the interlocking block paving project, and promote the high-quality development of the road yard of the water transportation project.
