根据多年的水准观测资料,京沪铁路北京至济南段沿线的北京、廊坊、天津、沧州、德州、等城市及周边地区由于多年大量的抽取松散堆积层的地下水,致使区域地下水位下降,导致地层压密,引起了不同程度的地面沉降,形成了多个沉降中心,区域地面沉降对京沪高速铁路北京到济南段将产生一定影响,特别是局部地区可能存在的不均匀地面沉降会对高速铁路工程产生一定影响。为此,开展区域地下水开采与地面沉降关系的研究并预测工程沿线地面沉降的发展趋势。
According to years of observation data, the groundwater table in Beijing, Langfang, Tianjin, Cangzhou, Texas and other areas along the Beijing-Shanghai Railway along the large-scale extraction of loosely packed groundwater has led to the decline of groundwater table in the area, The formation of a number of subsidence centers, the regional land subsidence on the Beijing-Shanghai high-speed railway Beijing to Jinan section will have a certain impact, especially in some areas may exist uneven subsidence of high-speed railway The project has a certain impact. To this end, carry out regional groundwater mining and land subsidence research and predict the development trend of land subsidence along the project.
