摘要:
输水管材选型面临环境特殊性、管材性能与成本之间的多重矛盾，管材选型直接影响工程投资成本、运行安全和工程效益。传统管材比选方法往往侧重于管材初始投资成本，而忽视了管材在整个生命周期内成本与性能的综合考量。为解决这一关键问题，引入价值工程理论，旨在构建一套系统化的输水管材全生命周期比选模型。该模型贯通了管材从生产、运输、建设安装、运行维护直至报废处置的全生命周期成本核算体系，量化了各阶段长期影响因素下的成本构成，尤其是漏损、能耗等隐性长期成本。同时，根据工程特点，创新性地将管材安全性、可靠性、耐久性等关键性能指标与全生命周期成本在同一维度上进行综合评价。以典型工程为例，对钢管（SP）、球墨铸铁管（DIP）、预应力钢筒混凝土管（PCCP）及混凝土保护层预应力钢筒混凝土管（PCCPC）等常用管材进行实证分析。结果表明，该模型能有效甄别出全生命周期价值最优的管材，该方法突破“初始投资成本优先”的传统思维，实现输水管材技术性能与经济性的平衡，为类似工程在管材选择和投资优化方面提供科学依据。
Abstract:
The selection of water transmission pipes involves multiple contradictions, such as the specific environmental conditions, the balance between material performance and cost. The choice of pipes directly affects the project investment cost, operational safety and overall project benefits. Traditional pipes comparison and selection methods often focus on the initial investment cost while neglecting a comprehensive consideration of the material’s cost and performance throughout its life-cycle. To address this critical issue, value engineering theory is introduced with the aim of constructing a systematic lifecycle comparison and selection model for water transmission pipes. The model integrates a life-cycle cost (LCC) accounting system for pipes, covering the entire life-cycle from production, transportation, construction and installation, operation and maintenance to decommissioning and disposal. It quantifies the cost components influenced by long-term factors at each stage, with particular focus on hidden long-term costs such as water leakage and energy consumption. Meanwhile, based on the characteristics of the project, key performance indicators such as safety, reliability and durability of the pipelines are innovatively evaluated in the same dimension as the life-cycle cost. Using a typical project as a case study, an empirical analysis was conducted on commonly used pipelines, including steel pipe (SP), ductile iron pipe (DIP),prestressed concrete cylinder pipe (PCCP) and concrete-cover prestressed concrete cylinder pipe layer (PCCP-C). The results show that this model can effectively identify the pipe with the optimal life-cycle “value”. This method breaks through the traditional mindset of “initial investment cost priority” and achieves a balance between the technical performance and economic efficiency of water transmission pipes, providing a scientific basis for material selection and investment optimization in similar projects.
