本文对巴西的南部地区,压实后的坡残积土料,在某些方面做了广泛的有关工程特性的研究,旨在应用于为开发这一地区水力资沅计划中,土坝的设计和施工。土料特性的判断,采用了图表型式,既反映了孔隙压力系数与强度指标之间的关系,又指出了不同密度对这种关系的影响。 In this paper, in the southern part of Brazil, after compaction, the residual soil material in the slope has been extensively studied in some aspects related to the engineering characteristics, and it is intended to be applied to the development of the area’s hydraulic resources planning and earth dam design. construction. The judgment of the characteristics of soil materials adopts a graph type, which not only reflects the relationship between the pore pressure coefficient and the strength index, but also points out the influence of different densities on this relationship.
