摘　　要：本文探讨了云南高原泥炭上沉积环境、沉积相、微观地质特征及工程地质特性。研究表明；云南高原泥炭上主要为晚更新世以来滞水构造盆地湖沼相沉积，与一般软粘土相比，有特殊的微观地质特征和工程地质特性。是性质极差的超软弱性土。This paper probes into the depostitional environments and precipitation factes andengineering geological characters of the peat soils in YunNan Plateau. The results show thatthe peat soils in YunNan Plateau deposited mainly in bad-drained structural basin by lakeand marsh from time of later Pleistocene Epoch. Compare with soft clay soils,the ndcrogeological characters and the engineering geological characters are very bad, the peat soils arevery soft soils.
