摘要: 针对目前关于对拉锚索支护结构理论和试验研究较少的情况,自行设计和完成了考虑施工过程的对拉锚索支护结构室内模型试验。研究表明:对拉锚索支护结构支护桩内力及桩顶位移的最大值均出现在施工过程中,而非施工完成状态;不同的开挖支护时机对桩身内力及土压力的分布存在较大影响;总结出了对拉锚索支护结构桩身内力、土压力以及挡板土压力的分布。

Abstract: In view of little theoretical and experimental research on pulling anchor supporting structure currently, the indoor model test of the pulling anchor supporting structure was designed and completed independently. Analysis of the test results reveals that the maximum values of internal force of pile and the displacement at the top of the pile both appear in the construction process, rather than the completion of the construction. Different time of excavating and supporting has great influence on the internal force of pile and the distribution of soil pressure. The distribution characteristics of the internal force, the soil pressure and the soil pressure of the baffle in the pulling anchor supporting structure are concluded.

Key words: geotechnical engineering, pulling anchor, supporting pile, internal force of pile, soil pressure, adjacent deep foundation pit
