使用说明与常见问题How-to & FAQ

「挡土墙砌块计算器」是什么？What is the Retaining Wall Calculator tool?

按挡土墙长度、高度和砌块尺寸计算砌块和压顶块数量，可加一层埋入地下的底层，并估算基础碎石和墙后排水碎石的体积。Count retaining wall blocks and cap blocks from the wall length, height and block size, with an optional buried first course, plus the gravel for the base trench and the drainage zone behind the wall.

如何使用「挡土墙砌块计算器」？How do I use the Retaining Wall Calculator tool?

在「挡土墙砌块计算器」中，填写「墙长（英尺）」、「地面以上墙高（英尺）」、「砌块长度（英寸，示例 12）」、「砌块高度（英寸，示例 4）」、「压顶块长度（英寸，0 = 不用压顶）」等参数，结果会随输入实时计算并显示在下方。In the Retaining Wall Calculator: Fill in "Wall length (ft)", "Wall height above ground (ft)", "Block length (in, example 12)", "Block height (in, example 4)", "Cap block length (in, 0 = no caps)"; results are recalculated instantly as you type.

砌块数量怎么算？How are the blocks counted?

每层块数 = 墙长 ÷ 砌块长度，层数 = 墙高 ÷ 砌块高度，都向上取整；勾选埋入底层时再加一层（很多厂家要求第一层埋入地下）。压顶块数 = 墙长 ÷ 压顶块长度。Blocks per course = wall length ÷ block length and courses = height ÷ block height, both rounded up; tick the buried course to add one more (many makers require the first course below grade). Caps = wall length ÷ cap length.

多高需要工程设计？When is an engineered design needed?

美国很多地方的规定是，墙高超过 4 英尺（约 1.2 米，从基础底部量起）或墙上方有附加荷载时，需要持证工程师设计并申请许可。具体以当地建筑法规为准。In many US jurisdictions, walls over 4 ft (about 1.2 m, measured from the bottom of the footing) or walls carrying a load above them need a design by a licensed engineer and a permit. Check your local building code.
