| 摘 要： | 通过在支护桩的冠梁内埋设钢筋应力计，对某深基坑冠梁内力进行现场测试，据此分析了冠梁受力特性及冠梁内力和弯矩随基坑开挖进程的变化规律。研究表明，冠梁是一个受弯构件，内力和弯矩值随基坑开挖进程不断变化，冠梁外侧两端受拉力作用，中间部位受压力作用；内侧两端受压力作用，中间受拉力作用。

| Abstract: | Based on the measured internal force by embedding rebar stress gauges in the top beam of retaining pile for a certain deep excavation, behavior and changing pattern of internal force and bending moment in excavation process are studied in this paper. The conclusion is drawn that top beam is a bending component, whose internal force and bending moment will vary with soil excavation, whose outboard ends suffer tensile force action while mid pressure action, whose inner ends suffer pressure action while mid tensile force action. |

| Keywords: | deep excavation top beam field test internal force bending moment |
