基于现有研究成果,通过文献调研等方法,归纳总结了影响湿式喷射法混凝土施工质量的工艺因素及其作用规律,对比分析了现行规范中关于喷射混凝土施工质量的检验评定方法。在此基础上,结合实际工程经验得到了隧道工程中采用湿式喷射法施工时各工艺参数的合理控制值。从喷射混凝土的实际作业环境和检测条件出发,阐明其标准强度值和实体强度值的区别,指出现行评定方法的适用性及局限性。最后,结合现行的GB 50086—2015《岩土锚杆与喷射混凝土支护工程技术规范》,给出喷射混凝土质量实体强度检验评定的建议方法,以期更加有效、合理地指导现场实际施工和质量控制与管理。

Based on the exiting research achievements, by using the method of literature investigation, the process factors affecting the quality of shotcrete with wetsprayed method, and their function laws are summarized. Also, the quality inspection and evaluation methods in current specifications are compared and analyzed. On this basis, combined with practical engineering experience, the reasonable control values of various process parameters in the construction of tunnel engineering with wetsprayed method are obtained. Moreover, starting from the actual working environment and testing conditions of shotcrete, the difference between standard strength value and entity strength value is clarified, and the applicability and limitation of current assessment method are pointed out. At last, according to one of current specifications, i.e. Technical code for engineering of ground anchorages and shotcrete support (GB 500862015),an entity quality evaluation method of shotcrete is suggested, which can guide actual construction and quality control and management in field more effectively and reasonably.
