摘　　要：选定同一路基横断面,用理正岩土5.1软件设计出相同安全系数的重力式挡土墙和衡重式挡土墙,利用ANSYS软件分别对二者加固路基的抗震性能进行了模拟计算。通过拟静力法和有限元法计算出两种挡土墙的支护抗震性能,从其位移云图分析比较表明,在静力作用和安全系数相同的情况下,只考虑水平地震力,两种挡土墙的抗震效果是一致的。On the same subgrade cross section,gravity retaining wall and balance weight retaining wall with the same safety factor are designed using Leading Geotechnical 5.1 Software and simulation calculation is carried out on their earthquake resistance for subgrade reinforcement using ANSYS software.Earthquake resistance is calculated separately for these two types of retaining wall through pseudo static method and finite element method.It is indicated from displacement diagram that under the same static effect and safety factor,only considering horizontal earthquake force,these two types of retaining wall have consistent earthquake resistance.
