摘要
以南沙地面沉降区域为研究对象,运用GMS软件模拟分析压缩土层、建筑荷载、地下水位等要素对地面沉降的影响程度,采用试错法,建立有效的地面沉降模型,并结合现状及历史数据进行预测和推演,模拟多种工况下南沙区地下水水位变化和地面沉降的变化量,结果表明:南沙区地面沉降较为严重的区域主要集中在龙穴岛北部,其建筑荷载造成的沉降量最大可达到 149 mm.该模型的构建及运用为南沙区在地面沉降管理决策方面起到良好的辅助作用,具有应用性和实践意义.
Abstract
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.
