摘要 随着宿州市建设的快速发展,大量抽取地下水使土层中的有效压力加大,导致地面高层逐渐下降,加上宿州市周围地区地下煤炭等资源开采严重,也导致地下水位下降.本文主要对宿州市区建立沉降监测网,通过周期性的观测获得沉降数据生成监测点沉降曲线,分析宿州市地面沉降趋势,绘制出宿州市地表沉降分布图,研究地表载荷分布对城市地表的影响、城市周边矿区开采对城市沉降的影响以及地下水影响因子,最后做出综合分析并对沉降区进行预测. Along with the rapid development of the urban construction of Suzhou,pumping underground water in large quantities increases the effective pressure of soil layer,which leads to the subsidence of higher land. The exploitation of underground coal of surrounding regions of Suzhou City is serious,which also leads to the groundwater recession. The main content of the paper is about the building of subsidence monitoring network in Suzhou City,the formation of settlement curve according to periodic observation,analyzing the land subsidence trend of Suzhou City,drawing out the distribution diagram of the surface subsidence of Suzhou City,researching the influence of the distribution of land loading on the urban land,the influence of the diggings exploitation in peri- urban areas on the city settlement,and influence factors of underground water,and finally performs a comprehensive analyze and forecasts the depression areas.
