Abstract:

为了预测垃圾土的沉降量,以便指导填埋场的建设以及封场利用,基于线性加载情况下垃圾土的沉降变形曲线呈“S”型这一特征,指出可用Usher模型预测其沉降随时间的变化规律,通过分离变量法,结合初始条件对建立的Usher模型求解,得到模型解的表达式。通过分析可知,Logistic模型和Gompertz模型是Usher模型的特例。采用重复二元回归法对Usher模型参数进行求解,利用该模型对某填埋场的沉降量进行了计算,通过计算可知,Usher模型的误差平方和为108.19,而Logistic模型和Gompertz模型的误差平方和分别为162.21和952.41。对比结果说明,Usher模型具有较高的预测精度,对同类工程的沉降预测具有一定的指导意义。
