摘要
根据排水管道顶管施工的投资特点,以《市政工程投资估算指标》中提供的数据为基础,采用优化拟合方法,以标准剩余差最小为目标函数,经逐次逼近拟合,获得的表达形式简单、计算精度满足工程要求的简化函数模型,可用于工程设计及方案比选。
According to the investment characteristics of drainage pipe jacking construction, based on the data of ＂municipal project investment estimation index＂, the simplified function model which the calculation accuracy can meet the engineering requirements was established by optimization fitting method, through the successive approximation fitting, and by the standard residual difference minimum as the objective function. The simplified function model can be used for engineering design and scheme comparison.
