Influence zones for 2D pile-soil-tunnelling interaction based on model test and numerical analysis
Abstract
In the congested urban areas, tunneling close to existing structures or services often occurs due to the lack of surface space. Consequently, tunneling-induced ground movements may cause a serious damage to the adjacent structures. This study focused on two-dimensional laboratory model test for the pile-soil-tunnelling interaction using a close range photogrammetric technique and numerical analysis. Model testing equipments and procedures were introduced, particularly the use of aluminium rods regarded as the frictional granular material. The normalized pile tip movements were identified by both the model test and finite element analysis. The model test results found to be in good agreement with the finite element analysis. Based on the normalised pile tip settlements due to tunneling adjacent to a line of loaded piles, influence zones were proposed influence zones

影响根据模型试验和数据分析的第2堆土壤挖洞互作用的区域
摘要
在被充塞的市区，挖洞接近现有的结构或服务经常发生由于缺乏表面空间。 结果，挖洞导致的地面运动也许造成对毗邻结构的一个严重损坏。 使用一个近距离摄影测量的技术和数据分析，这项研究集中于二维堆土壤挖洞互作用的实验室模型试验。 介绍了式样试测器材和做法，被认为摩擦颗粒状材料特殊使用铝标尺。 正常化的堆技巧运动是由模型试验和有限元分析确定的。 被发现的模型试验结果在与有限元分析的利益协定。 基于正常化的堆技巧解决由于挖洞在被装载的堆附近线，影响区域提议在早先研究中比那些相对地宽和深提议的影响区域。 作者相信决定隧道建筑的合理的地点计划阶段的将是有用的
影响区为二维桩土相互作用掘进基于模型试验及数值分析
摘要
在拥挤的城市地区，掘进接近现有结构或服务，常常发生因为缺乏地面空间。因此，掘进诱发地面运动可能造成严重损害的毗邻建筑物。本研究的重点是两维实验室模型试验桩土相互作用掘进用近景摄影测量技术和数值分析。模型试验设备和程序相继出台，特别是使用铝杆视为摩擦颗粒材料。归桩端主义运动所确定的两个模型试验和有限元分析法。模型试验结果发现，在一个很好的协议，与有限元分析。根据对正常桩端住区由于隧道旁的一排装桩，影响区提出了影响区是相对更加广泛和深入的，比那些建议，在以往的研究中。作者认为，这将是有益的，以决定合理的位置，隧道施工，在规划阶段。
