鹅卵石铺多厚？

装饰性覆盖 5 厘米，抑制杂草 7.5–10 厘米。粒径较大时仅为盖住下面的土工布就需要更大厚度。

一立方码鹅卵石有多重？

约 2,400–2,700 磅，即 1.2–1.35 吨。同粒径下圆形石料比碎石轻，因为石块之间空隙更多。

一吨鹅卵石能铺多大面积？

厚 5 厘米时约 11.6 平方米，7.5 厘米时约 8 平方米，10 厘米时约 6 平方米。

鹅卵石下面要铺土工布吗？

铺在土面上的花坛需要，它能防止石料下陷并抑制杂草。请用机织土工布，不要用容易撕裂并成片翻上来的薄膜。

花坛该用石子还是覆盖物？

石子无需更换也不会被风吹走，但会蓄热且一旦长草很难清理。覆盖物分解后能改良土壤，但每年都要补充。

公式

体积 ft³ = 长 × 宽 × (厚 in ÷ 12) × (1 + 损耗)   ·   吨数 = ft³ × 密度 ÷ 2000

参考资料

Measure what the tool asks for
This calculator works from 长度 in ft, 宽度 in ft and 厚度 in in. Measure the finished area you are covering, not the material — an estimate is only as good as the dimensions you feed it.
What it does with those numbers
体积 ft³ = 长 × 宽 × (厚 in ÷ 12) × (1 + 损耗) · 吨数 = ft³ × 密度 ÷ 2000 Every figure on the page comes out of that one expression, so you can check it by hand.
Why it adds 5% waste
5% 用于沉降以及散落到划定边界之外的部分。
Choosing a 石料粒径
提示：粒径越大石块之间空隙越多，每立方码反而更轻，计算器会自动调整密度。
Where the numbers come from
The constants are taken from ASTM D448 — Standard Sizes of Aggregate for Road and Bridge Construction and USDA NRCS — Landscape mulch and ground cover guidance, linked in full below. If a figure here disagrees with your supplier's spec sheet, use the spec sheet — it describes the product you are buying.
What this will not tell you
This is a material takeoff, not a bid. It does not price labour, permits, delivery, equipment hire or site preparation, and it assumes a straightforward layout. Complex cuts, difficult access and awkward shapes all cost more than the geometry suggests.

常见问题

把长、宽、厚（英尺）相乘，再乘以约 95 lb/ft³ 并除以 2,000。6 × 1.8 米的花坛铺 5 厘米约需 0.95 吨。
