摘　　要：以咸宁工点为例,运用太沙基固结理论,结合室内土工试验,用曲线拟合法,分别总结出了s-t的关系式和计算出了完成沉降需要的时间。同样对其他两个具有代表性的工点进行了相同研究,总结出了武广客运专线红粘土地基的沉降与时间之间的关系式以及完成沉降需要的时间,对武广客运专线设计和施工具有指导意义。This text illustrates with the Xianning spot, and combines with its data of geotechnical test and Terzaghi consolidation. The author summarizes the function between settlement and time and the time requires for the whole settlement. At the same time, adding it with other two results of different spots, the author summarizes the relation between the settlement and the time and the time requires for the settlement about the special line of passenger traffic＇s red clay foundation along Wuhan to Guangzhou, which can guide the practice of engineering.
