摘要

泥炭土的承载力低、压缩性大,给建筑工程带来了巨大挑战。有几种土壤改良方法可以解决这些问题。石灰和水泥稳定法是提高土壤质量的一种可行方法。本研究旨在调查石灰和水泥混合物对研究地点土壤物理和机械性能的影响。研究结果显示,原始土壤的 CBR(加利福尼亚承载比)值为 5.60%。在特定的混合物变化中,CBR 值有所增加,原土 + 3% 石灰 + 5% 水泥混合物的 CBR 值达到 11.56%。这种混合物可用于路基,满足筑路路基 6% 的 CBR 要求。原土+10%石灰+10%水泥混合料的 CBR 值为 26.50%。符合筑路标准的路基 CBR 值为 20% 至 30%。添加石灰和水泥混合物来稳定泥炭土可以显著提高泥炭土的承载能力,增加混合物中石灰和水泥的比例可以提高 CBR 值。

Optimization of a mixture of lime and portland composite cement (PCC) for stabilizing peat soil in road construction
Peat soil presents significant challenges in construction due to its low bearing capacity and high compression. Several soil improvement methods are available to address these issues. One viable approach to enhancing soil quality is through lime and cement stabilization. This research aims to investigate the impact of a lime and cement mixture on the physical and mechanical properties of the soil at the research location. The research results reveal that the CBR (California Bearing Ratio) value for the original soil is 5.60%. CBR values increased in specific mixture variations, with the CBR value for the original soil + 3% lime + 5% cement mixture reaching 11.56%. This mixture can be employed in the subgrade, meeting the CBR requirement for road construction subgrade, which is 6%. In the case of the mixture involving the original soil + 10% lime + 10% cement, a CBR value of 26.50% was achieved. The CBR value for subgrade with outstanding criteria for road construction is 20% to 30%. The addition of a lime and cement mixture for peat soil stabilization can significantly enhance the soil's bearing capacity, and increasing the percentage of lime and cement in the mixture leads to higher CBR values.
