The cost model of regional water resource systerm is established by analyzing and projecting a plenty of datum about each part and using curve fitting compaction method. 通过对搜集的大量给水、污水处理、中水系统建设费用及运行费用资料进行统计分析和系列设计,运用曲线拟合方法,建立水资源系统工程费用函数。
Use of existing test data, derived using curve fitting each detection point backfill the degree of compaction of the linear equation to calculate the settlement of backfill. 利用现有检测数据,用曲线拟合法得出每个检测点回填土压实度的直线方程,由此计算回填土的沉降。
