| 摘 要： | 预应力混凝土围护桩用于基坑围护有其独特的优越性,但是此桩作为临时性的大变形构件,本身的受力性能与普通的受弯、受剪构件有所区别,本文将对此桩适用的理论模型、挠度和裂缝的约束、异号时变弯矩对抗剪性能的影响等问题进行探索研究。

| Abstract: | There are special advantages for the application of new I-shaped prestressed concrete pile in pit maintenance. However, the pile. , as a temporary and large deform constructional element , has a distinguish stress performance in flexural property and shear property with common beam. We will research and explore the problems, such as the suitable theoretical model for pile , the restraint of deflection and crack and the influence to shear property due to opposite time varying bending moment and so on. |

| Keywords: | strut-and-tie model crack opposite time varying bending moment |
