津秦客运专线滨海北站是综合交通枢纽站,是该专线的重要节点。本文基于该工程的地质背景条件和地质灾害监测资料进行分析,对其范围内的地面沉降、饱和粉(砂)土液化和水土腐蚀地质灾害的发育现状进行探讨与分析,并依次应用2阶多项式回归分析、标准贯入试验法、取样分析法分别进行了预测分析,结果表明在现状条件下,本工程近五年地面沉降速率有所减缓,饱和粉(砂)土液化灾害等级为轻微液化一中等液化,浅层水土腐蚀对工程基础中的钢筋混凝土的腐蚀性为中腐蚀。通过进行现状分析和趋势预测,从而为地质灾害防治和确保铁路的安全运营提供信息。
津秦客運專線濱海北站是綜閤交通樞紐站,是該專線的重要節點。本文基于該工程的地質揹景條件和地質災害鑑測資料進行分析,對其範圍內的地麵沉降、飽和粉(砂)土液化和水土腐蝕地質災害的髮育現狀進行探討與分析,併依次應用2階多項式迴歸分析、標準貫入試驗法、取樣分析法分彆進行瞭預測分析,結果錶明在現狀條件下,本工程近五年地麵沉降速率有所減緩,飽和粉(砂)土液化災害等級為輕微液化一中等液化,淺層水土腐蝕對工程基礎中的鋼觔混凝土的腐蝕性為中腐蝕。通過進行現狀分析和趨勢預測,從而為地質災害防治和確保鐵路的安全運營提供信息。

North Binhai station is a crucial transportation junction of Tianjin-Qinhuangdao Passenger Dedicated Line. This paper, based on the analysis of North Binhai Station geological condition and existing geological disaster monito- ring data, first analyzes the station's present geological disaster situation including land subsidence, saturated silts/ sands liquefaction and water and soil corrosion. Then the paper gives a predictive analysis of above geological disaster situation through second-order polynomial regression model analyses, standard penetration test and sampling respec- tively. And the result indicates that in the next five years, if the current situation remains, land subsidence will slow down, saturated silts/sands liquefaction grade will be light liquefaction to middle liquefaction and shallow groundwater and soil corrosion will be moderately corrosive. By the analysis and projection above, this paper intends to provide useful information for the geological disasters prevention and safe railway operation.
