近年来由于在深厚软土层上建造大型工业建筑、高层房屋以及港口码头工程日渐增多,因此对于饱和软粘土处理方法的研究深为人们重视。深层搅拌法加固软粘土技术是利用水泥作为固化剂,通过特制的深层搅拌机械在地基深部就地将软粘土与固化剂强制拌和,使软粘土硬结而提高地基强度。这种地基加固新方法在国外(主要是日本)是七十年代中期才开始在工程中实际应用。国内由交通部水运规划设
In recent years, due to the increasing construction of large-scale industrial buildings, high-rise buildings, and harbor wharfs on deep soft soil layers, the study of saturated soft clay treatment methods has been given much attention. The deep mixing method to reinforce soft clay is to use cement as a curing agent. The special deep mixing machine is used to force the soft clay and hardener to mix in place deep in the foundation to make the soft clay hard and improve the strength of the foundation. This new method of ground reinforcement has only been applied in engineering since the mid-1970s (mainly in Japan). Domestic Ministry of Transport Water Transport Planning
