摘　　要：工程结构在短期和长期使用寿命方面设计不当时,工程结构的稳定性将无法得到保证。通过改变有效的结壳厚度和强度、地基和路堤参数,对工程结构稳定性达到特定安全系数(FOS)所需的拉力大小进行了综合分析。在GEO5软件中使用一种切片方法,该方法可以适应可变的土壤条件以及孔隙水压力参数,并讨论了不同厚度和强度的结壳覆盖下软土路堤的时变特性。The stability of engineering structures cannot be guaranteed due to improper design of engineering structures in terms of short-term and long-term service life.In this paper,by changing the effective crust thickness and strength,foundation and embankment parameters,a comprehensive analysis of the tensile force required for the stability of engineering structures to reach a specific factor of safety(FOS)is carried out.A slicing method is used in GEO5 software,which can adapt to variable soil conditions and pore water pressure parameters.The time-varying characteristics of soft soil embankments covered with crusts of different thickness and strength are discussed.
