Various applications of biopolymer-based soil treatment (BPST) in geotechnical engineering have been implemented in recent years, including dust control, soil strengthening and erosion control. Despite BPST methods can ensure the effectiveness of engineering while meeting environmental protection requirements, BPST technology requires further validation in terms of site applicability, durability, and economic feasibility. This study aims to provide a state-of-the-art review and future prospective of BPST. Current biopolymer types, engineered and assessed in laboratory scales, are described along with site implementation attempts. The effect of biopolymers on soil behavior is reviewed with regard to geotechnical engineering application and practice, including soil consistency limits, strength parameters, hydraulic conductivity, soil-water characteristics, and erosion control. The economic feasibility and sustainability of BPST application in ground improvement and earth stabilization practices is discussed. This review postulates biopolymers to be a promising new, environmentally friendly ground improvement material for geotechnical and construction engineering practice.

近年来，基于生物聚合物的土壤处理（BPST）在岩土工程中的各种应用已得到实现，包括粉尘控制，土壤加固和侵蚀控制。尽管BPST方法可以在满足环保要求的同时确保工程的有效性，但是BPST技术仍需要在现场适用性，耐用性和经济可行性方面进行进一步验证。这项研究旨在为BPST提供最新的综述和未来前景。描述了目前在实验室规模内进行工程设计和评估的生物聚合物类型，以及现场实施的尝试。综述了岩土工程应用和实践中生物聚合物对土壤行为的影响，包括土壤稠度极限，强度参数，水力传导率，土壤水特征和侵蚀控制。讨论了在地面改良和地球稳定实践中应用BPST的经济可行性和可持续性。这篇评论假设生物聚合物是一种有前途的，对岩土工程和建筑工程实践来说是环保的新型地面改良材料。
