研究结论:P-Q-t曲线分析法、钻孔出水量分析法、注浆量分析法、检查孔出水量测定、检查孔稳定分析是高压富水断层注浆效果检查评定的必测方法。其中,钻孔出水量分析法和检查孔出水量测定是对堵水作用的检查,P-Q-t曲线分析法、注浆量分析法和检查孔稳定分析是对加固作用的检查。对于检查孔允许出漏水量标准,通过齐岳山隧道F11高压富水断层现场试验以及多个注浆循环的检验证明,采用2 L /min?m是可行的、可靠的。
Abstract：Research purposes: The research is done on the examination and evaluation method and standard for the grouting effectunderhigh -pressure and rich -waterweak geological condition to provide the reference toworking out the criterion and standard for the similarengineering.
Research conclusions:The P -Q -tcurve analysismethod, the analysismethod for the yieldingwaterquantity from the bore, the grouting quantity analysismethod, the determination ofyieldingwaterquantity from the check -up bore, and the check -up bore stability analysismustbe used forexamining and evaluating the grouting effect to the high –pressure and rich -water faul.t The analysis method for the yielding water quantity from the bore and the determination of yieldingwaterquantity from the check -up bore are used forexamining the ponding effec.t The P -Q -tcurve analysis method, the grouting quantity analysis method and the check -up bore stability analysis are used for examining reinforcing effec.t The on -site tests and several grouting cycle tests forF11 high -pressure and rich -water fault of Qiyueshan Tunnel show the standard of2 litres perminute /permeter for the yieldingwater from the check -up bore is feasible and reliable.
