CONSTRUCTION QUALITY MANAGEMENT TECHNOLOGY OF GUIZHOU EXPRESSWAY TUNNEL

According to the main problems of domestic and international highway tunnel project construction quality, construction quality management technology was discussed in detail, with the actual situation of some tunnel constructed in Guizhou Province in recent years. One, geological conditions and geological problems should be analysis in detail. Two, a targeted Geological Forecast method should be chose to imply comprehensive geological forecast. Different construction measures were suggested according to monitoring measurement data and different geological problems exposed in tunnel construction. To protect the quality of construction, quality tests of advance and initial support system should be done in target. Comprehensive quality testing should be done after all construction projects completed. As analysis, tunnel construction quality management was a system, which needs a variety ways combined with point and plane, with qualitative and quantitative, with macro control and subtle management. Thus highway tunnel project construction quality and management technology could be upgraded to a new height.
