Abstract
During the construction of the inclined shaft of a railway tunnel, the groundwater was found well-developed, and the surrounding rock was of mainly gravel soil with high clay content. Though the original design intended to use curtain grouting and advanced small ductile grouting, the site grouting effect was not obvious as expected. Water and mud bursting were serious during the construction, and brought negative effects to slag-out, and serious influence on the construction progress. In view of this situation, some optimization programs such as adjusting the profile grade of inclined shaft, adding advanced horizontal borehole to drain the water were put up to accelerate the construction of gallery, so as to enable the gallery to assist the tunnel construction and meet the progress schedule. Practices have well proved the efficiency of the optimization programs.关键词
