摘　　要：水泥搅拌桩是深层地基加固施工中的重要技术,在我国应用广泛,发展成熟,而东南亚等国家应用案例较少。经过查阅收集资料,文章选取中国交建马来西亚东海岸铁路项目,探讨水泥搅拌桩在东南亚地区有机质土软基处理中的应用,主要针对软土较深(深8~15 m)、有机质含量较高(14%~22%)的水泥搅拌桩室内配比及成桩问题进行简要分析,并提出合理化建议。Cement mixing pile is an important technology in deep foundation reinforcement construction. It is widely used and mature in China, but there are few application cases in Southeast Asia and other countries. After consulting and collecting data, this paper selects the China Communications Construction Malaysia East Coast Railway Project to discuss the application of cement mixing pile in the soft foundation treatment of organic soil in Southeast Asia. It briefly analyzes the indoor proportioning and pile forming of cement mixing pile with deep soft soil( 8-15 m deep) and high organic matter content( 14%-22%), and puts forward reasonable suggestions.
