中国青藏地区边坡牛顿力及地应力监测数据集（2022-2023）

本数据为中国青藏高原地区多个滑坡灾害牛顿力监测预警数据和地应力监测数据，监测地区包括四川宝兴、四川北山、云南丽江、四川汶马、西藏林芝等。滑坡灾害牛顿力监测预警数据通过北斗卫星监测平台在实验数据平台中心获取，可以实时获取监测位置的深部牛顿力的变化，并根据滑坡牛顿力预警准则判定监测区域是否会发生滑坡灾害，若发生牛顿力突降则根据突降变化程度及时反馈给主管部门。此数据可为活动断层诱发的临震区滑坡灾害防治提供科学指导。地应力监测数据通过新型压磁地应力监测传感器获取，为确保观测数据的稳定性和可靠性，监测探头一般安装于钻孔静水位以下80m以深的完整基岩中，并设置对比补偿元件以标定温度、气压等环境变化因素导致的数据漂移偏差，此数据用于监测活动断裂的应力变化情况，可为断层失稳监测提供可能的预测数据。

This dataset comprises Newton force monitoring and early warning data for landslide disasters and geostress monitoring data collected across multiple sites in the Qinghai-Tibet Plateau region of China. The monitored areas include Baoxing, Beishan in Sichuan Province, Lijiang in Yunnan Province, Wenma in Sichuan Province, Nyingchi in Tibet Autonomous Region, and others.

The Newton force monitoring and early warning data for landslide disasters is obtained via the Beidou Satellite Monitoring Platform at the experimental data platform center. It can acquire in real time the variations in deep Newton force at monitoring locations, and judge whether a landslide disaster will occur in the monitored area based on the landslide Newton force early warning criteria. If a sudden drop in Newton force is detected, the system will timely send feedback to the competent authorities according to the magnitude of the sudden change. This dataset can provide scientific guidance for the prevention and control of landslide disasters in seismically imminent areas induced by active faults.

The geostress monitoring data is collected using novel magnetostrictive geostress monitoring sensors. To guarantee the stability and reliability of the observed data, monitoring probes are typically installed in intact bedrock at a depth of over 80 meters below the static water level of boreholes. Comparative compensation components are configured to calibrate data drift deviations caused by environmental fluctuations such as temperature and atmospheric pressure. This data is utilized to monitor stress changes along active faults, and can offer potential predictive data for fault instability monitoring.
