昆明滇池泥炭土力学性质改良试验

滇池泥炭土工程力学性质较差，为适应大规模开展工程建设的需要，需对泥炭土工程力学性质进行改良。本文采用正交试验方法对滇池泥炭土在添加不同配比的水泥、石灰、石膏等固化剂条件下的改良效果进行分析，得到了试验条件下最佳固化剂配比方案：水泥6%，石灰6%，石膏粉0.5%。结果表明，滇池泥炭土经改良处理后力学性质得到了一定的改善，由高压缩性土变为中压缩性土，抗压强度也有所提高。

Experiment on Improving Mechanical Character of Dianchi Peat Soil in Kunming

The mechanical character of dianchi peat soil is poorer,and must be improved in order to meet the need of the large-scale engineering construction.Through the orthogonal experiment,analyses have been made of the influences of adding cement,lime,gypsum with different volume ratio on mechanical character of peat soil.The best proportioning under experimental conditions was summed up as follows: cement 6%,lime 6%,gypsum 0.05%.The result shows that the mechanical character of peat soil in Dianchi is improved after adding cement,lime and gypsum.The compressibility of peat soil from high to nearly low,in addition,compressive strength has also improved.
