土方系数计算（Earthwork coefficient calculation） Earth conversion (2008-01-10 20:23:47) reprint labels: Gossip Summed up the general excavation is natural; compacting, embankment compaction, borrowers are generally ordinary soil, natural dense square. If the loan words should be multiplied by the coefficient of soil 0.87. to take the 0.80 to 0.92 by the hard soil. For example: One of the distinctive features of the new quota is in the subgrade soil rock engineering, considering the conversion coefficient between the natural and the compaction density, due to the use of this factor, in the calculation and allocation of the number of subgrade soil, rock excavation, we should consider this factor, which should not be simply according to section volume allocation. For Subgrade Earthwork engineering, excavation by natural dense volume calculation, calculation, fill volume after pressing so as to fill and compaction volume for engineering quantity, using natural compacting party as the calculating unit, the quota should be multiplied by the provisions of the conversion coefficient. The chapter explains the fixed coefficient, which transport column in the quota specified in the chapter, suitable for artificial excavation of Zengyun quota and motor dump trucks, tractors, earthmoving truck transport earthwork transportation quota. This coefficient include increasing the wastage cost for earth rock engineering project quota quota level are compiled in the section of the embankment construction, the efficiency level is low concentration of soil soil field. To borrow, the quota items in the calculation of the digging and loading, can put the number of parts, including the loss of earthwork completed by the artificial mechanical consumption, but for transportation, there is not much difference between the two situations, the same considerations on loss, increase the cost of manual and machinery. The quota chapter shows the coefficient using the rules illustrated as follows: On a line (
