文登抽水蓄能电站地下厂房施工仿真分析

Abstract

抽水蓄能电站地下厂房洞室群具有规模大，洞室多，结构型式多等特点。为探讨立体开挖方法缩短厂房开挖工期的可能性，以文登抽水蓄能电站为例，本文对其地下厂房顺层开挖方案与两种不同的立体开挖方案进行了施工全过程仿真计算。计算结果表明：立体开挖在技术条件和机械投入允许的情况下，短期内的机械设备的高投入可以缩短总工期，从而带来显著的效益，对类似工程具有参考意义。 The obvious characteristics of the caverns of underground plant of pumped-storage power station are large scale, many caverns and many structure types. In order to explore the possibility of shortening the project duration of the Three-dimensional excavation method, taking the Wendeng Pumped Storage Power Station as an example, the whole construction process simulations of un-derground excavation in sequence plan and two different 3D excavation plans were carried out. The results show that the short-term high input of mechanical equipment can shorten the total construction period and bring significant benefits when technical conditions and the input of ma-chinery are allowed. This study is of great reference significance for similar projects.
