昆明泥炭及泥炭质软土的工程特性研究

Study on Engineering Characteristics of Peat and Peaty Soft Soil in Kunming

昆明地区的软土主要为淤泥质土、淤泥、泥炭质土、泥炭,其中强泥炭质土、泥炭全国少见,其极差的工程特性对建筑工程、道路工程、桥梁梁头接合部位等具有较大危害。对昆明滇池湖相沉积软土中较典型的泥炭质土、泥炭的成因,分布及特性,物理力学指标进行分析研究,为在昆明地区的工程建设选择合理的基础形式和恰当的地基处理方法提供参考。

The soft soils in Kunming are mainly mucky soil, sludge, peaty soil and peat, in which the strong peaty soil and peat are rare in the country. The poor engineering characteristics of peaty soil and peat have the great harm to the joint positions of building engineering, road engineering and bridge beam. The article analyzes and studies the causes, distributions, characteristics and physical mechanical indexes of the more typical peaty soil and peat in the lacustrine sediment soft soil of Dianchi Lake in Kunming, which can be referred for selecting the reasonable foundation form and the proper subgrade treatment method of the engineering construction in Kunming.
