Influence of tunnelling on pile foundations. The effects of tunnel construction on the behaviour of existing pile foundations will be investigated. In particular, models will be developed to predict the influence of tunnel excavation on the bearing capacity, average settlement, differential settlement and tilt of pile groups and the loads and bending moments induced in the piles of the group and the pile cap. These models will allow rational assessment of the effects on buildings undermined by tunnels. This work is significant and timely because of the growing trend to place transport infrastructure underground in many cities of the world.

隧道施工对桩基的影响。此外，我们亦会研究隧道施工对现有桩基的影响。特别是，将建立模型来预测隧道开挖对群桩承载力、平均沉降、差异沉降和倾斜度的影响，以及群桩和承台中的荷载和弯矩。这些模型将使人们能够理性地评估隧道对建筑物的影响。这项工作意义重大，也很及时，因为在世界许多城市，将交通基础设施建在地下的趋势越来越大。
