GB 4814—84
本標(biāo)準(zhǔn)適用于所有樹種的原木材積計算。
1 檢尺徑自4~12 cm的小徑原木材積由公式
V=0.7854L(D+0.45L+0.2)2÷10,000
確定。
2 檢尺徑自14 cm以上的原木材積由公式
V=0.7854L〔D+0.5L+0.005L2+0.000125L(14-L)2·(D-10)〕2÷10,000
確定。
兩式中:V── |
材積,m3; |
L── |
檢尺長,m; |
D── |
檢尺徑,cm。 |
3 原木的檢尺長、檢尺徑按GB 144.2—84《原木檢驗 尺寸檢量》的規(guī)定檢量。
4 檢尺徑4~6 cm的原木材積數(shù)字保留四位小數(shù),檢尺徑自8 cm以上的原木材積數(shù)字,保留三位小數(shù)。

圓材材積計算公式
(補充件)
A.1 檢尺長超出原木材積表所列范圍而又不符合原條標(biāo)準(zhǔn)的特殊用途圓材,其材積按下式計算:
V=0.8L(D+0.5L)2÷10,000
A.2 圓材的檢尺長、檢尺徑按GB 144.2—84《原木檢驗 尺寸檢量》的規(guī)定檢量。
A.2.1 尺寸進(jìn)級及公差
A.2.1.1 檢尺徑:按2 cm進(jìn)級。
A.2.1.2 檢尺長的進(jìn)級范圍及長級公差允許范圍由供需雙方商定。
A.3 缺陷限度及分級標(biāo)準(zhǔn)由供需雙方商定。
A.4 地方煤礦用的坑木材積按下表計算:
