无砟轨道服役状态监测系统徐兰高铁验证测试数据集

西安地铁一号线下穿咸阳西货场、陇海铁路、徐兰高铁路基段，地铁隧道盾构下穿前，对徐兰高铁、陇海铁路路基进行预加固处理。为保证下穿隧道施工期间和施工后结构状态安全、稳定、可靠，监测内容主要包括以下内容：列车运行安全性参数、轨道结构部件受力、轨道结构的稳定性指标、轨道结构刚度指标、轨道结构部件与基础振动加速度。Xi’an Metro Line 1 passes under the subgrade sections of Xianyang West Freight Yard, Longhai Railway and Xuzhou-Lanzhou High-speed Railway. Preliminary reinforcement treatment was conducted on the subgrades of Xuzhou-Lanzhou High-speed Railway and Longhai Railway prior to the shield tunneling of the metro tunnel passing under these infrastructures. To ensure the safety, stability and reliability of the structural states during and after the underpass tunnel construction, the main monitoring contents include the following: train operation safety parameters, forces of track structural components, stability indicators of track structures, stiffness indicators of track structures, and vibration acceleration of track structural components and their foundations.
