【摘要】 在指数曲线配合法的基础上 ,提出了一种新的反推固结系数的方法———等比级数法 ,并以某高速铁路软土试验路堤的实测沉降曲线为依据 ,用这两种方法分别推算固结系数并进行比较分析 ,结果表明 :等比级数法推算的固结系数变化规律明确 ,并能避免指数曲线配合法产生的误差影响 ,其值与室内试验测定值比较 ,属于同一数量级。更多还原

【Abstract】 Based on the exponential curve fitting method, a new method for calculating the consolidation coefficient-the geometric progression method was put forward.And based on the settlement observation curve of the trial embankment of an express railway on soft clay ground, two kinds of methods were compared and analyzed by calculating the consolidation coefficient.The results showed that the rule of va riation of consolidation coefficient calculated by the geometric progression met hod was clear, and it could avoid the influence of error brought by the exponen tial curve fitting method.The results of the geometric progression method and th e laboratory test belonged to the same order of magnitude.更多还原
