摘要
卤水井开采对其附近的铁路桥梁桩基带来严重的危害,采用数值模拟的方法,在现场监测数据的基础上,分析了采取不同卤水井开采距离抽水时,桥梁桩基的沉降及内力变化特点。研究结果可为地下水开采造成的铁路桥梁沉降治理工作提供决策依据。
The exploitation of brine well is harmful to the pile foundation of railway bridge nearby. Based on the field monitoring data, in this paper, numerical simulation method is used to analyze the characteristics of settlement and internal force of bridge pile foundation with different mining distance. The research results can provide decision basis for the settlement control of railway bridges caused by groundwater exploitation.
