摘　　要：通过工程实例,得出粉土作为充填物的大尺度土工织物充填袋的各项参数,给出充填压应力与袋体周向拉力之间的关系,并得出一定规格的土工织物充填袋的填筑流失率。通过分析地基沉降位移数据,在确保地基稳定的条件下,调整了沉降位移控制标准,使施工效率得到提高,且缩短了施工工期,降低了施工成本。Based on the project example, we obtain the parameters of large-scale geotextile bag filled with silt, give the relationship between the filling pressure stress and circumferential force between the bag bodies, and get the turnover rate of the filling bags of certain specifications. Based on the analysis of the foundation＇ s settlement displacement, we adjust the standard controlling the settlement displacement under the prerequisite of guaranteeing the stability of the foundation, and achieve the objective of improving the construction efficiency, shortening the construction period, and cutting down the construction cost.
