This dataset is mainly aimed at the research and protection needs construction of water related slope freezing hazards in the northwest cold and freeze-thaw environment. Based on the temperature field monitoring observation station of Liugou Reservoir bank slope in Xinjiang, multi-point temperature measurement cables mainly record temperature monitoring data.
The time range of this dataset is from 13:00 on July 20, 2019 to 15:00 on September 11, 2021. The time accuracy of this dataset is 1 hour. The spatial scope involves two monitoring cross-sections, recording a range of approximately 20m × 7m and 15m × 7m respectively. Since it does not involve three-dimensional spatial coordinates, this spatial accuracy is not considered. The temperature probe adopts the "multipoint temperature measuring cable" of State Key Laboratory of Frozen Soil Engineering, with an accuracy of ± 0.05 ℃. The working principle of multi-point temperature measurement cable is to use the law of the conductivity of an object changing with temperature to measure temperature. When there is a small change in temperature, the resistance value of the thermistor will change significantly. As long as the resistance value of the thermistor is measured, the corresponding temperature can be calculated based on the functional relationship. When using a thermistor thermometer for ground temperature observation, embed the thermistor in the designed measuring point position, lead the wire out of the ground, measure the resistance value of the line, and calculate the temperature of the corresponding measuring point according to the calibration function. When processing each group of thermistor thermometers, a full-length wire is used as a common circuit, which is directly led to the measuring end. Weld one end of the thermistor to the common wire position corresponding to the measuring point, and lead the other end to the measuring end with a wire. Connect the wire to the corresponding terminal terminal according to the measuring point number, and finally install all the wires into the protective sleeve.
This dataset generated a total of 18591 sets of data, covering temperature and hydraulic data of slope monitoring along the reservoir bank. The first line is the numbering of each borehole. The second line is the ground temperature data obtained by monitoring the actual probes of each borehole at a height above the ground. The real-time temperature data at each temperature detection point is measured from the third to the last line. The first column shows the generation time of each set of data, and the second to tenth columns show the monitored ground temperature data of hole 1 #. The measurement point numbers from front to back are 1 # 1, 1 # 2, 1 # 3, 1 # 4, 1 # 5, 1 # 6, 1 # 7, 1 # 8, and 1 # 9, corresponding to the ground temperature data at depths of 0.00m, 0.25m, 0.50m, 0.75m, 1.00m, 1.50m, 2.00m, 2.50m, and 3.00m in hole 1 #. The eleventh to twenty third columns show the monitored ground temperature data of hole 2 #, with the measurement point numbers from front to back being 2 # 1, 2 # 2, 2 # 3, 2 # 4, 2 # 5, 2 # 6, 2 # 7, respectively. 2 # 8 and 2 # 9 correspond to the ground temperature data at depths of 0.00m, 0.30m, 0.60m, 1.00m, 1.50m, 2.00m, 2.50m, 3.50m, and 4.50m in the 2 # hole, respectively. Columns 20 to 28 are the monitored ground temperature data for the 3 # hole. The measurement point numbers from front to back are 3 # 1, 3 # 2, 3 # 3, 3 # 4, 3 # 5, 3 # 6, 3 # 7, 3 # 8, and 3 # 9, respectively, corresponding to 0.00 in the 3 # hole m. The ground temperature data at depths of 0.30m, 0.60m, 1.00m, 1.50m, 2.00m, 2.50m, 3.50m, and 4.50m, as well as the monitoring ground temperature data of hole 4 # from column 29 to column 37, are numbered 4 # 1, 4 # 2, 4 # 3, 4 # 4, 4 # 5, 4 # 6, 4 # 7, 4 # 8, and 4 # 9 from front to back, corresponding to the ground temperature data at depths of 0.00m, 0.30m, 0.60m, 1.00m, 1.50m, 2.00m, 2.50m, 3.50m, and 4.50m inside hole 4 #, respectively.
