中文摘要:
      我国幅员辽阔,具有大面积的盐碱地、有机质土,地下咸水区也分布较广。且随环境的恶化及我国近代工业化的推进,除去天然腐蚀性土外越来越多的土地受到污染变为腐蚀性土。对腐蚀性土进行改性处理及达到二次利用的目的,多采用硅酸盐水泥对其进行固化。水泥加固腐蚀性土多用于其原腐蚀环境中,易使加固体发生劣化,强度衰减情况较为显著。本文对不同性质的腐蚀性土进行分类并对其研究进展进行归纳总结,对水泥加固腐蚀性土强度变化机理进行论述,总结影响水泥加固腐蚀性土强度变化的因素。对有关水泥加固腐蚀性土强度特征问题研究不足之处进行讨论,为水泥土加固腐蚀性土未来研究方向提出展望。
英文摘要:
      China has a vast territory, with a large area of saline-alkali land and organic soil, and the underground salt water area is also widely distributed.With the deterioration of the environment and the advancement of modern industrialization in China, more and more land outside the natural corrosive soil is polluted into corrosive soil.For the purpose of modifying the corrosive soil and achieving secondary utilization, it is mostly cured by Portland cement.Cement-reinforced corrosive soil is mostly used in its original corrosive environment, which tends to deteriorate the solidification and the strength attenuation is more significant.n this paper, the corrosive soils with different properties are classified and their research progress is summarized. The mechanism of strength change of cement-reinforced corrosive soil is discussed, and the factors affecting the strength change of cement-reinforced corrosive soil are summarized.The insufficiency of research on the strength characteristics of cement-reinforced corrosive soils is discussed, and the future research directions of cement-soil-reinforced corrosive soils are proposed.
