间隔型基坑开挖效应的离心机模拟试验研究

Centrifugal model tests on excavation effect of interval foundation pits

  • 摘要: 采用离心机模型试验,研究间隔型基坑群同时开挖情况下对周围既有结构物与基坑围护结构的影响。试验采取停机开挖的方式分六步进行基坑开挖,获得每一个开挖顺序下车站墙体、隧道墙体以及基坑围护结构不同位置的变形,最后分析相应结构在间隔型基坑群同时开挖情况下的变形规律。本研究可为日后类似工程的设计施工提供一定参考。

     

    Abstract: The centrifugal model tests are used to study the excavation effects of interval foundation pits on the adjacent structures and the retaining walls. The tests adopt the generalized similarity ratio of 200 to carry out the scale simulation. The foundation pits are excavated in six steps of the shutdown-excavation method. The deformation data at different positions of the station walls, the tunnel walls and the retaining walls in each step are obtained. Finally, the deformation rules of the structures close to the interval foundation pits are drawn by analyzing these data. This study may provide some reference for the design and construction of similar projects in the future.
