| 摘 要： | 盾构隧道作为一个三维问题，其横向性能与纵向性能是密切联系的，将其横向和纵向割裂为两个平面问题，虽然可使问题简单化，但无法考虑纵横向性能的匹配关系。在横向修正惯用法的基础上，将横向弯曲刚度有效率引入到纵向等效连续化模型的推导中，对考虑横向刚度影响的盾构隧道纵向等效抗弯刚度进行理论推导，得到了考虑横向刚度有效率的纵向等效抗弯刚度计算式，从而初步将纵向刚度的分析与横向刚度的变化统一起来，进而也说明了盾构隧道纵、横向抗弯刚度的相关性和匹配性。实例分析表明：盾构隧道横向抗弯刚度的大小与纵向等效抗弯刚度关系密切，表现为同方向、近线性关系变化，即纵向抗弯刚度随横向抗弯刚度的增大而增大。

| Abstract: | As a three-dimensional structure,the transverse and longitudinal characteristics of a shield tunnel are closely correlative.Although it simplifies the three-dimensional problem by separating it into two plane problems,the relationship between the transverse and longitudinal characteristics cannot be taken into account in the analysis process.On the basis of the amendatory habitual analytical method,the longitudinal equivalent rigidity is deduced by considering the introduced transverse rigidity efficiency i... |
