| 摘 要： | 对于深基坑工程问题的研究，围护结构大多简化为线弹性梁单元模型，该分析方法不能准确反映钢筋混凝土结构的实际受力情况。以杭州地铁一号线试验段秋涛路车站深基坑为工程背景，建立能够考虑钢筋与混凝土实际受力情况的非线性三维实体模型，对咬合桩这一特殊形式围护结构的受力机制进行了分析。通过与现场实测结果比较和分析，验证了计算方法的正确性，为今后类似工程的设计计算、开挖施工提供了理论依据。

| Abstract: | Linear elastic model is common used to analayze retaining structure of deep foundation pit excavation, which is an approximate treatment in some aspects, such as material compose, material characteristics and so on. There will be some warp in the analysis with this model compared with practical situation. Based on the practical project of Qiutao Road Station excavation of Hangzhou Metro No.1. A nonlinear solid model is established to study the loading mechanism of secant piles. Compared with the measured results, it is shown that this method is vaild and it can be applied to the deep foundation pit design and construction. |
