以变形观测点的平均高程作为研究对象,对连云变电所地面沉降规律进行研究。在沉降区域内较均匀地布设一些能反映地面沉降情况的观测点,定期对其进行沉降观测,求得每期观测点的高程值。选用Gompertz曲线模型和Logistic曲线模型进行拟合,建立预测模型,对研究对象进行预测并进行精度评定。通过研究发现,该方法能较好地反映地面整体沉降情况,可以作为研究地面沉降的方法之一。
Taking the average elevation of deformation observation point as the research object, the land subsidence law of Lianyun Substation is studied. In the subsidence area, some observation points that can reflect the land subsidence are distributed more evenly, and the subsidence observation is conducted periodically to obtain the elevation value of each observation point. Gompertz curve model and Logistic curve model are selected for fitting, the prediction model is established, the research object is predicted and the accuracy is evaluated. Through the research, it is found that this method can better reflect the overall settlement of the ground and can be used as one of the methods to study the land subsidence.
