施工用电永临结合设计方法及技术经济比较

Design method and techno-economic analysis of combined permanent and temporary power supply for construction

根据石太客运专线南梁、太行山隧道施工用电永临结合设计情况,介绍施工用电永临结合的设计基础及外部电源调查的必要性,重点阐述如何确定施工用电负荷,并从技术、经济角度论述施工用电永临结合的可行性、合理性。

Based on the design for combined permanent and temporary power supply for the construction of Nanliang and Taihangshan tunnels on Shijiazhuang-Taiyuan passenger dedicated line, this article makes an introduction to the basis of the design for the combined power supply for construction and the necessity of investigating external power sources. It mainly expounds how to determine the electric load for construction and elaborates from the economic angle the feasibility and rationality of the combined power supply for construction.
