| Abstract: | The Shanggai Hydropower Station expansion project is located in Napo County of Guangxi.Its diversion tunnel is accommodated in surrounding rock with poor engineering geological condition.After construction scheme comparison,pre-grouting and excavation scheme was adopted.The results of construction demonstrate that application of pre-grouting technique is capable of fixing the surrounding rock of excavated tunnel accommodated in weak strata,ensuring construction safety,rendering less cost and tunneling well. |
