隧道衬砌检测判识标准及缺陷处理措施研究
Study on Detection Standard of Tunnel Lining and Defects Treatment Measures
摘要
Abstract
In view of the fact that the defects behind the lining of the tunnel are not described in detail in the current specification, and combining with the geological radar detection results of a railway tunnel under construction and the necessity whether the problems need further processing, the void defect behind the lining is separated from the non-dense defect. It is considered that when the line length of a single maximum cavity body in the not-dense area is less than or equal to the small value between the steel arch spacing and excavation footage, and the disconnection distance Li of the cavity on the radar measuring line is less than or equal to 50 cm, it is judged as not-dense where the line length of a cavity is larger than the steel arch spacing or excavationfootage, and it is determined that the lining is void behind the lining. Not-dense defects can only be avoided in future construction by improving the construction process without rework processing. The original defects of dense, not-dense and cavity are classified into dense, not-dense, void and cavity to allow easier understanding of the results by the decision maker to determine tunnel defect treatment measures more accurately according to the detection results.关键词
