减少复杂地质隧洞超挖研究

Research on the reduction of over-excavation in complex geological tunnel

在滑坡体治理工程中,减少复杂地质隧洞超挖,具有明显的经济性。针对这一关键性问题,本QC小组展开了现状调查,根据实际情况对隧洞出现超挖情况进行调查、分析,并制定了相应对策。对策实施后,减少了复杂地质隧洞超挖,保证了工期,节约了施工成本。

It has obvious economic efficiency to reduce over-excavation of complex geological tunnels in the landslide governance project. The QC group investigates current status aiming at the critical problem. The over-excavation condition in the tunnel is investigated and analyzed according to actual condition. Corresponding After the countermeasures are implemented, over-excavation of complex geological tunnels is period is guaranteed, and the the construction cost is saved.
