山东滨莱高速隧道群长期服役性能试验数据

“山东滨莱高速隧道群长期服役性能试验数据集”主要对山东滨莱隧道群围岩压力、喷射混凝土应力、钢架应变、纵向连接筋应力、初期支护和二次衬砌之间的接触压力，二次衬砌混凝土内、外侧混凝土应力和二次衬砌内、外环向钢筋应力等进行监控量测。其中，应力监测采用钢弦式传感器和MWT2172振弦采集仪，并对数据进行预处理（重复数据删除、缺失值插补等），获得准确、完整、一致的公路隧道结构状态全寿命监控量测数据集。

Long-term Service Performance Test Dataset of Tunnel Group on Shandong Binlai Expressway: This dataset mainly conducts monitoring and measurement on multiple parameters of the tunnel group on Shandong Binlai Expressway, including surrounding rock pressure, shotcrete stress, steel frame strain, longitudinal connecting reinforcement stress, contact pressure between primary support and secondary lining, internal and external concrete stresses of secondary lining concrete, as well as internal and external circumferential reinforcement stresses of the secondary lining. For stress monitoring, vibrating wire sensors and MWT2172 vibrating wire data collectors are adopted. Afterwards, data preprocessing operations such as duplicate data removal and missing value imputation are performed to obtain an accurate, complete and consistent full-life monitoring and measurement dataset for highway tunnel structural conditions.
