2021-2023年南宁膨胀土边坡土壤湿度计监测数据

数据集为广西南宁膨胀土边坡实测土壤湿度数据，数据时间范围为2021年-2023年。降雨会诱发滑坡灾害，这与膨胀土的胀缩性、裂隙性、超固结等特性有关，其中更深层的因素之一便是土壤湿度，土体在干湿循环下产生裂隙，进而导致土体强度降低，引发灾害。

This dataset contains in-situ measured soil moisture data collected from expansive soil slopes in Nanning, Guangxi, with the time span ranging from 2021 to 2023. Rainfall can trigger landslide disasters, which are related to the characteristics of expansive soil such as swell-shrinkage behavior, fissurability and overconsolidation. One of the deeper underlying factors is soil moisture: cracks form in the soil under dry-wet cycles, which reduces the soil strength and ultimately leads to geological disasters.
