    • A retaining wall block can include a top surface and opposing bottom surface, a front surface and opposing rear surface, and first and second opposing side surfaces. A projection can extend downwardly from the bottom surface and can include a forwardly facing indexing surface oriented generally parallel with the front surface of the block. The indexing surface can be configured to engage a rearwardly facing surface of a block in a lower course of blocks. The block can also include a pair of spaced apart key slots defined in the rear surface. Each key slot can include an enlarged interlocking portion and a throat portion extending from the interlocking portion to the rear surface. An assembly can be created whereby a pair of correspondingly shaped keys of an elongate barrier member are engaged with key slots of block so as to inhibit rearward horizontal displacement of the keys within the key slots. Elongate barrier member can include a body presenting an inner surface and an outer surface and a pair of opposing ends, each opposing end defined one of the keys. The inner surface of the barrier member and the rear surface of the block can together define a core region for receiving fill material.
    • 挡土墙块可以包括顶表面和相对的底表面,前表面和相对的后表面,以及第一和第二相对的侧表面。 突起可以从底表面向下延伸并且可以包括面向大致平行于块的前表面定向的朝前的分度表面。 分度表面可以构造成在块的下部过程中接合块的面向后的表面。 该块还可以包括限定在后表面中的一对间隔开的键槽。 每个键槽可以包括从互锁部分延伸到后表面的放大互锁部分和喉部。 可以创建一个组件,由此细长的阻挡构件的一对对应的形状的键与块的键槽接合,以便阻止键在键槽内的向后水平位移。 细长的阻挡构件可以包括呈现内表面和外表面的主体以及一对相对的端部,每个相对端限定一个键。 阻挡构件的内表面和块的后表面可以一起限定用于接收填充材料的芯区域。
