| 摘 要： | 提出了计算沉入式大圆筒结构筒后土压力的新方法。在研究过程中引入土拱效应的概念,考虑了圆筒变位模式对土压力分布的影响。取筒后微分土条进行受力分析,得到求解土压力的基本微分方程,并求得其解析解。通过与实验数据比较可知,计算方法与实测值符合较好。

| Abstract: | A new calculation method of the earth pressure distribution on the back side of embedded large cylinders is proposed. In the course of the study, the soil arch effect and the influence of cylinder displacement is taken into account. After taking analysis of equilibrium of forces on the strip element, the basic differential equation is established and its analytical solution is obtained.Comparison with experimental results shows that the proposed method is in good agreement with the measured values. |
