摘　　要：为应对建筑工人短缺,推进电站绿色施工,小断面TBM在抽水蓄能电站排水廊道和自流排水洞得到广泛运用。与常规TBM使用场景相比,抽水蓄能电站地下洞室具有洞径小、距离短、孤段多、转弯急、坡度大的特点。现在的水电定额体系中缺少相关子目,而且水利工程及市政工程中的定额与抽水蓄能电站的特点不相匹配。本文以5个正在使用小断面TBM施工的电站为样本,现场测定施工消耗量,为预算定额编制提供借鉴。In order to cope with the shortage of construction workers and promote the green construction of power stations,small-section TBM is widely used in drainage corridors and gravity drainage tunnels of pumped storage power stations.Compared with the conventional TBM application scenario,the underground cavern of pumped storage power station has the characteristics of small tunnel diameter,short distance,many isolated sections,sharp turn and large slope.The current hydropower quota system lacks relevant subitems,and the quotas in water conservancy projects and municipal projects do not match the characteristics of pumped storage power stations.In this paper,five power stations under construction with small crosssection TBM are taken as samples,and the construction consumption is measured on the spot,which provides reference for budget quota compilation.
