豌豆砾石铺多厚？

装饰覆盖 5 厘米，经常行走的步道 7.5 厘米。游乐设施下方 CPSC 建议 23–30 厘米，这是完全不同的量级。

一吨豌豆砾石能铺多大面积？

厚 5 厘米时约 11.6 平方米，7.5 厘米时约 7.7 平方米，2.5 厘米时约 23 平方米。

豌豆砾石适合做车道吗？

单独使用不适合。它是圆粒，永远不会互相咬合，会在轮胎下滚动并向两侧迁移。车道请用带棱角的碎石。

豌豆砾石需要边界条吗？

需要。没有约束的圆粒石会四处扩散，一个季节内没有收边的步道就会中间变薄、两侧堆积。

游戏区用豌豆砾石安全吗？

它是被认可的松铺材料，但必须达到规定厚度：CPSC 对 1.5 米以内跌落高度要求 23 厘米。此外它不便于轮椅通行。

公式

体积 ft³ = 长 × 宽 × (厚 in ÷ 12) × (1 + 损耗)   ·   吨数 = ft³ × 96 ÷ 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 × 96 ÷ 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% 用于散落到边界之外以及沉入基土的部分。
Where the numbers come from
The constants are taken from ASTM D448 — Standard Sizes of Aggregate and CPSC Public Playground Safety Handbook — loose-fill surfacing depths, 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 96 lb/ft³ 并除以 2,000。6 × 1.2 米的步道铺 5 厘米约需 0.64 吨。
