用于沼泽地开发、河道开挖、清淤作业的水陆两用履带式工程机械,平均接地比压一般不超过0.2kg/cm~2,有的甚至小于0.1kg/cm~2。此种机械在履带宽度方向上的比压不能假定是均布的,而应该视为同其长度方向一样按一定规律变化的。一、由自重引起的平均接地比压目前,水陆两用式工程机械说明书中所给定的接地比压,大多是平均接地比压,说明它 For the amphibious track-type construction machinery used for wetland development, river excavation and dredging operations, the average ground pressure is generally not more than 0.2kg/cm~2, and some even less than 0.1kg/cm~2. The specific pressure of such a machine in the direction of the track width cannot be assumed to be uniform, but should be regarded as changing in the same manner as its longitudinal direction. First, the average ground pressure caused by the weight of the current ground pressure, water and land use engineering machinery specifications given in the ground pressure, mostly average ground pressure, indicating it
