摘要
施工前的方案优公是为了避免因设计原因给工程造成损失 ,同时也是神延线所有工程开工前的必做工作 ,寺则河隧道在工期短、围岩类别低、质量要求高、外资标单价低的情况下 ,施工前经过科学、合理地辅助坑道方案优化 ,使异常紧张的工期处于受控状态。笔者列出寺则河隧道辅助坑道优化的过程 ,以期能为类似工程施工提供参考。
The optimization of sheme before the construction is aimed at to avoid the losses in construction caused by design reasons.It was the necessory work which must be put forward before starting all engineering items for the Shenmu-Yan'an Railway.Before the construction of Sizehe Tunnel with th e situations of short construction period ,low class of surrounding rock, high q uality requirement and low unit bidding cost of foreign investments,a scientific and reasonable adit scheme was optimized so as to render the very intense const ruction period becoming an under-controlled situation.The procedures of the opt imization of the adit scheme for the Sizehe Tunnel are described in this paper,w hich may be provided as reference for constructing the similar engieering projec ts.
