【摘要】 该文对宁靖盐高速公路盐城北段的工程地质和水文地质进行了分析评价,对沿线软土和砂土液化特性进行了详细分析,统计分析了软土代表性物理力学指标之间的相互关系,对软土施工期间和工程竣工后路堤的稳定性进行了评估,计算分析了砂土液化的可能性和液化等级,得出了施工期间软土路基基本稳定和砂土具有轻微液化潜势的结论。更多还原

【Abstract】 The engineering geology and hydrogeology in the northern part of Yancheng city in Nin-Jing-Yan expressway was analyzed and evaluated.The liquefaction characteristics of soft clay and sand,and the relationship of representative physical and mechanical indexes of soft clay were statistically analyzed.The stability of highway embankment in the coures of construction and post construction was estimated,and calculated the possibility and degree of liquefaction of sand.It was concluded that soft soil subgrade is basically stable and sand has slight potential to liquefaction.更多还原
