Abstract：The optimization of scheme before the construction is aimed at to avoid the losses in construction caused by design reasons. It was the necessary work which must be put forward before starting all engineering items for the Shenmu-Yan'an Railway. Before the construction of Sizehe Tunnel with the situations of short construction period，low class of surrounding rock, high quality requirement and low unit bidding cost of foreign investments，a scientific and reasonable adit scheme was optimized so as to render the very intense construction period becoming an under-controlled situation. The procedures of the optimization of the adit scheme for the Sizehe Tunnel are described in this paper, which may be provided as reference for constructing the similar engineering projects.
