滇中引水工程大坡度长斜井提升运输能力研究

Research on lifting capacity of long inclined shafts with large slope at Central Yunnan Water Diversion Project

由于隧洞埋深、地形、地质、投资等众多因素限制了深埋长隧洞建设,大坡度长斜井在“长隧短打”的工程中得到了越来越多的应用,其提升运输能力决定了斜井方案的设计。以滇中引水工程香炉山隧洞2号施工斜井为例,对大坡度长斜井的提升运输能力进行了详细分析并提出了具体施工措施方案。实践证明,该措施可以满足施工要求。研究成果可为类似工程提供参考。

Due to the limitation of many factors in construction of deep buried long tunnels,such as tunnel depth,topography,geology,investment,etc.,long inclined shafts with large slope have been used widely in the process of"long tunnel and short drilling".The lifting capacity of transportation determines the design of inclined shaft scheme.No.2 construction inclined shaft of Xianglushan Tunnel for Central Yunnan Water Diversion Project is tak⁃en as an example to carry out a specific analysis for lifting and transportation capacity of long inclined shafts with the large slope,and construction measures are put forward in this paper.The case shows that the proposed measures can meet the construction requirements.This research results can provide a reference for similar projects.
