一、序言混凝土砌块路面包括混凝土砌块层及处于基底层之上的砂垫层。砌块和垫层的两侧通常用路缘石加以侧向限制,如图1所示。这种侧限连同砌块隙缝中受振动的砂,以及砌块形状或铺砌形式一起所提供的约束,保证了砌块间的咬合作用得以发挥和保持,因此个别砌块不致脱离其毗邻砌块而单独地发生水平或垂直移动。这种咬合作用具有扩散 I. Preface Concrete block pavement includes concrete block layer and sand cushion layer above the base layer. Both sides of the block and cushion are usually laterally restrained by curbs, as shown in Figure 1. This confinement, together with the vibrations of the sand in the block gaps and the constraints provided by the block shapes or paved forms, ensures that the inter-block bite can be exerted and maintained so that individual blocks do not break away from their adjacent blocks While horizontal or vertical movement occurs separately. This bite has spread
