摘要

本文对透水路面中混凝土砌块形状的影响进行了研究。介绍了不同排水槽几何形状块体的一系列水力性能试验,以确定其对入渗能力的影响。铺装样品在专门设计的实验室装置中进行测试,该装置由变梯度测试架、雨水模拟器和集水室组成。该装置考虑到坡度变化和两种水输入:输入径流和地表直接降雨。在三种不同堵塞状态和四种坡度下,对四块不同形状的开槽混凝土砌块进行了测试。所得结果初步得出了砌块几何形状对路面水力性能影响的结论,对路面设计具有指导意义。

The influence of paving-block shape on the infiltration capacity of permeable paving
This paper reports on an investigation into the effects of the shape of concrete paving blocks used in permeable pavements. It describes a series of hydraulic performance tests on blocks with different drainage slot geometries, in order to determine their influence on infiltration capacity. Paving samples were tested in a purpose-designed laboratory rig consisting of a variable-gradient testing frame, rain simulator and water-collecting chambers. The apparatus allowed for slope variations and two inputs of water: input runoff and direct rainfall over the surface. Four differently shaped slotted concrete blocks were tested under three different clogging states and four gradients. The results obtained lead to initial conclusions about the influence of block geometry on the hydraulic performance of paving which have implications for pavement design.
