土壤的状态不同,则土方容量也不同。通常可以区别为:自然状态(未挖掘状态)、挖松状态和夯实状态三种情况。若取某一状态下的土方量为1,其它状态下的土方量数值可用土方量换算系数f换算而得。计算挖掘机、装载机铲斗容量时,一般均以松方表示,而土方量却又常以自然状态或夯实状态计算。因此,计算工程机械的生产率 Different soils have different earth capacity. Usually can be distinguished as: natural state (excavation state), loose state and compaction state three conditions. If the amount of earthwork in one state is taken as 1, the amount of earthwork in other states can be converted by the conversion factor f of the earth mass. When calculating the capacity of shovels of excavators and loaders, they are usually expressed in loose squares, while the amount of earthwork is often calculated in natural state or compacted state. Therefore, calculate the productivity of construction machinery
