摘要:
文章选择京沪高速铁路沿线的北京、廊坊、天津、沧州、德州等几个沉降中心的监测数据及研究资料,对比分析发现地面沉降发展与地下水位变化密切相关,依此建立了地面沉降与地下水位变化的经验关系,进一步分析预测了华北平原各主要沉降区地面沉降发展趋势。结果表明:北京地区地面沉降变化与水位变化线性相关明显,地面沉降对地下水位变化反应较灵敏,无明显临界水位;廊坊、天津及沧州地区显示指数相关,有较明显的临界水位,沉降过程存在初期缓慢沉降和快速沉降两个阶段;德州市在监测时段内显示二次函数相关,可能存在临界水位,但不如天津至沧州地区明显。各主要沉降区除天津市区地面沉降已经得到有效控制外,随着地下水资源的不断超采,过量消耗深层地下水储量,其它沉降区的地面沉降将持续发展,地面沉降灾害问题也必将日趋严重。
Abstract:
By examining the correlation between land subsidence and groundwater level variation,we can predict the development trend of land subsidence in the North China Plain with reasonable accuracy.Contrasting with the monitoring data of land subsidence in such cities as Beijing,Langfang,Tianjin,Cangzhou and Dezhou along the high speed railway form Beijing to Jinan,the relativity between land subsidence and changes in groundwater level is analyzed,the correlation formulas between land subsidence and gr...
