贵州高速公路隧道工程施工质量管理技术探讨

根据国内外高速公路隧道工程施工质量存在的主要问题,结合贵州省近年来修建的几条高速公路隧道工程的实际情况,提出高速公路隧道工程施工质量管理技术问题。首先,需要对具体的隧道工程所存在的工程地质条件及施工中可能存在的工程地质问题进行详细分析;然后,有针对性地选择地质超前预报方法,实施综合地质超前预报;并根据隧道施工过程中揭露的不同工程地质问题和隧道监控量测数据,采取不同的施工措施;为了保障工程施工质量,需要有针对性地开展隧道超前支护及初期支护质量检测;在工程全部施工完毕,进行衬砌质量全面检测。分析认为,隧道工程施工质量管理是一个系统工程,需要采取点面结合、定性与定量相结合、宏观控制与细微管理相结合的多种方式。只有这样,才能将高速公路隧道工程施工质量及管理技术提升到新的高度。

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.
