Ground improvement will be critically important in the present and future geotechnical practice for designing the structures in weak soil. This paper presents a review of the recent development in ground improvement techniques, especially chemical stabilisers. Various available chemical stabilisers are identified and compared with other available methods. Though the use of chemicals provides an excellent alternative to the traditional methods, they still lack proper understanding regarding their use, handling, application, and long-term effect on the environment. Various chemical stabilisers and their applicability conditions are summarised in the present paper. Insight of biochemical, electrochemical, inorganic, and organic stabilisers is presented with future scope of these methods along with the potential areas where a lot of efforts is needed to industrialise these methods are also discussed briefly. A need for developing a more environmentally friendly and safe method was felt while reviewing these methods. Lack of a large amount of data is a major concern for lesser use of these methods industrially. A lot of laboratory and field experiments should be conducted in different conditions to ensure safe results from chemical stabilisers.
在当前及未来的岩土工程实践中，地基处理对于在软弱地基上设计结构至关重要。本文综述了地基处理技术的最新进展，特别是化学稳定剂方面。识别了各种可用的化学稳定剂，并与其他可用方法进行了比较。尽管使用化学药剂为传统方法提供了绝佳的替代方案，但在其使用、处理、应用以及对环境的长期影响方面，仍缺乏充分的了解。本文总结了各种化学稳定剂及其适用条件。介绍了生化、电化学、无机和有机稳定剂的相关见解以及这些方法的未来发展前景，同时还简要讨论了需要付出大量努力才能将这些方法工业化的潜在领域。在回顾这些方法时，人们意识到需要开发一种更环保、更安全的方法。缺乏大量数据是这些方法在工业上较少使用的一个主要问题。应在不同条件下进行大量的实验室和现场试验，以确保化学稳定剂能产生安全的效果。
