Abstract

A major full-scale experiment (the TULIP - Tunneling and Limitations on the Impact on Piles - research project) was conducted in 2020 on Line 16 of the Grand Paris Express project (France). Its objective was to analyze the tunnel boring machine-soil-pile interactions occurring during tunnel excavation near piled structures in the context of the geology of the Paris basin. This data paper summarizes the main measurements made during this experiment, namely: (i) the horizontal and vertical displacements measured in the ground, on the surface and in the thickness of the cover, (ii) the settlements of the pile heads, and the variations of the normal forces in the pile depth. These data, interpreted in two articles cited in the references, may be of interest for the calibration of analytical and numerical models dedicated to the estimation of the impact of TBM excavation on neighboring constructions, in particular those based on piles.

摘要

2020年，在大巴黎快铁项目（法国）16号线开展了一项大型全面试验（TULIP——隧道挖掘及其对桩的影响限制研究项目）。其目的是在巴黎盆地地质背景下，分析在靠近桩基础结构的隧道挖掘过程中发生的隧道掘进机-土壤-桩相互作用。本数据文件总结了该试验期间进行的主要测量，即：（i）在地面、地表和覆盖层厚度中测量的水平和垂直位移，（ii）桩头沉降以及桩身深度处法向力的变化。参考文献中引用的两篇文章对这些数据进行了解释，这些数据可能有助于校准用于估算隧道掘进机挖掘对邻近建筑（特别是基于桩基础的建筑）影响的分析和数值模型。
