降雨条件下加筋土挡墙服役性能劣化机理与灾变控制数据集

加筋土挡墙在自然环境中会受到降雨入渗或地下水作用的影响，导致填料的力学特性与筋土界面特性发生劣化，进而影响加筋土挡墙的安全与稳定。为此，本研究采用室内试验、数值模拟与现场监测的方法分析含水率对挡墙填料及筋土界面力学特性的影响，探究降雨-列车荷载作用下加筋土挡墙力学响应与变形行为。本数据集旨在分析降雨条件下加筋土挡墙服役性能劣化机理，提出并验证灾变控制技术。数据集主要包括三个部分：含水率对挡墙填料与筋土界面力学特性影响的测试数据、降雨-列车荷载作用下加筋土挡墙力学响应测试数据、多雨地区加筋土挡墙现场监测测试数据。数据采集依托石家庄铁道大学土工实验室的精密仪器、广泛使用的商业软件、技术成熟的监测设备，确保了数据的准确性和可靠性。质量控制通过标准化试验与模拟流程来保证。本数据集可为揭示降雨条件下加筋土挡墙服役性能劣化机理与灾变控制提供关键数据支撑，具有重要的学术研究与工程应用价值。Reinforced earth retaining walls are subjected to rainfall infiltration or groundwater actions in natural environments, which cause deterioration of the mechanical properties of the backfill and the characteristics of the reinforcement-soil interface, thereby undermining the safety and stability of the reinforced earth retaining walls. To address this problem, this study adopts laboratory tests, numerical simulations and field monitoring methods to analyze the effects of water content on the mechanical properties of the retaining wall backfill and reinforcement-soil interface, and to investigate the mechanical response and deformation behavior of reinforced earth retaining walls under coupled rainfall-train loads. This dataset aims to analyze the degradation mechanism of the service performance of reinforced earth retaining walls under rainfall conditions, and to propose and validate catastrophe control technologies. The dataset primarily consists of three parts: 1) test data regarding the effects of water content on the mechanical properties of the retaining wall backfill and reinforcement-soil interface; 2) test data on the mechanical response of reinforced earth retaining walls under coupled rainfall-train loads; 3) field monitoring test data of reinforced earth retaining walls in rainy regions. Data collection relies on precision instruments from the Geotechnical Laboratory of Shijiazhuang Tiedao University, widely used commercial software and mature monitoring equipment, which guarantees the accuracy and reliability of the dataset. Quality control is ensured through standardized test and simulation procedures. This dataset can provide critical data support for revealing the degradation mechanism of the service performance of reinforced earth retaining walls under rainfall conditions and for catastrophe control, and has important academic research and engineering application value.
