昆明泥炭、泥炭质土的力学特性研究

昆明盆地由于阳光充足,水温适宜,又有湖泊、河流、洼地等地貌条件,有利于水生、湿生植物的生长蔓延,向沼泽化辟落发展,所以泥炭、泥炭质土的分布,是有其地区特点的。现建设现代新昆明,有许多建筑必须建设在这样的地基土上,因此,有关昆明泥炭、泥炭质土工程特性及工程应用的研究

Experimental Study and Analysis of Normalized Behavior on the Mechanical Characteristics of Peat & Peaty Soils in Kunming

The peat & peaty soil in Kunming is a kind of special soil, its physical and mechanical properties are different from usual clay or organic soil. Research on the mechanical characteristics of the stratum is of significance in both theory and in practice. In this paper, the mechanical characteristics of the peat & peaty soil in Kunming were studied using the unconsolidated-undrained triaxial shear tests and the consolidated-undrained triaxial shear tests under various confining pressure states. The relationship among axial stress, axial train and pore water pressure of the clay and the peat and peaty soil and the failure shape of soil sample were obtained as a special soil, its normalization is worth of further research.
