Research and Practical Application of Land Subsidence Model Based on GMS
This paper takes the land subsidence area of Nansha as the research object,uses GMS software to simulate and analyze the in-fluence of compressed soil layer,building load,groundwater level and other factors on land subsidence,adopts the trial-and-error method to establish an effective land subsidence model,and combines the current situation and historical data to predict and deduce.Simulating the vari-ation of groundwater level and land subsidence under various conditions,the results show that the most serious area of land subsidence in Nan-sha is mainly concentrated in the north of Longxue Island,where the maximum settlement caused by building load can reach 149mm.The con-struction and application of the model play a good auxiliary role in land subsidence management decision-making in Nansha District,and have practical significance.
