一、试验室求含砾石土壤的最大干容重目前在度验室内要求得含砾石土壤的密实度,大都采用苏联М.Я.切列金所著的“路基压实法”(人民交通出版社出版)所介绍的方法,即将含有砾石的土壤试样通过5公厘筛,将通过筛孔部分的土壤,按照标准捣实法,求出它的最大干容重,然后再将此最大干容重, First, the laboratory for gravel soil containing the maximum dry weight Currently required in the laboratory gravel soil density, mostly by the Soviet Union М.Я. Che Liejin “embankment compaction method” (People’s Communications Press Published) that the soil sample containing gravel through 5 mm sieve, through the mesh part of the soil, according to the standard tamping method, find its maximum dry bulk density, and then the maximum dry bulk density,
