对岩泽市、北海道和崎玉大宫市郊区的泥炭地进行了一系列的理化和力学试验，并对泥炭地和泥炭地的岩土性质进行了研究。各种物理化学测试的结果主要被总结为所涉及的有机质含量的函数。同时，利用孔压仪对泥炭和腐殖质碎屑的孔容和孔径分布随一维压缩的变化进行了研究。力学试验结果表明，有机质含量对土体的次压缩系数和渗透系数影响较大，纤维泥炭具有明显的各向异性抗剪强度。
A series of physico-chemical and mechanical tests were performed on the soils sampled from peaty grounds in the suburbs of Iwamizawa city, Hokkaido and Ohmiya city, Saitama, and the geotechnical properties of peats and peaty grounds were investigated. The results of various physico-chemical tests were mainly summarized as a function of organic matter content involved. Also, using the samples of peats and humused chipes, the changes of pore volume and pore size distributions with the one-dimensional compression were investigated with the porosimeter apparatus. From the results of mechanical tests, it was found that the coefficients of secondary compression and permeability of soils were strongly influenced by the amount of organic matter and fibrous peats remarkebly showed anisotropic shear strength.
