大庆地区湿陷性黑土研究

大庆南部地区分布着一种颜色发黑、结构松散、成分复杂、对水极度敏感的工程性质极差的地质材料 ,它兼有湿陷性土、有机质土、碱土和分散土等诸多特殊土的劣质特性。通过野外调查、原位测试和室内各种试验研究 ,对这种黑土的野外特性、成分结构、物理力学性质、承载力和湿陷特性、地层年代等进行了较系统的阐述和分析 ,并通过综合比较 ,将其定名为湿陷性黑土.

ON COLLAPSIBLE BLACK SOIL IN DAQING REGION

There is a kind of black geological material with loose structure, complex components, extreme sensitivity to water and inferior engineering properties in the southern region of Daqing City. It has all the inferior properties of collapsible soil, organic soil, alkali soil, dispersive soil and other special soils. On the basis of field investigation, in-situ tests and laboratory tests, this paper systemically characterized and analyzed the black soil including the field identification, component structure, physical and mechanical properties, bearing capacity, collapsible performance, and stratum age. As a result of a comprehensive comparison, the soil is named as collapsible black soil.
