The most common predictable approach to land subsidence is to choose, analyze and forecast a representative deformation observation points .If an uneven land subsidence (settlement) comes into being, the settlement rate of deformation observation points will be different. The analysis of the individual subsidence observation points can not reflect the true ground subsidence in the region . Instead, the comprehensive analysis of the information about all the deformation observation points can more objectively reflect the overall settlement of the region. This study makes use of all the observation points to establish a triangular mesh deformation, and uses the superposition of the Terrain surface TIN model and the design surface TIN model to obtain the earthvolume in the two surface triangular elements. Through the earthvolume, the size of the overall settlement of the ground situation can be indirectly reflected in order to adopt appropriate preventive measures . This paper studies the Earthvolume as a research object, employs Gompertz curve model to fit the data and design the forecast model to make accurate assessments.The research shows that this method can reflect the overall total ground settlement,and explore the laws of the land subsidence when an uneven settlement arises.
