研究目的：对高压富水软弱地质条件下注浆效果的检测评价方法和标准进行了研究，为类似工程规范和标准的制定提供参考。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、检孔出水量的确定，对高压富水地层的注浆效果必须进行检孔稳定性分析来检验和评价。采用钻孔出水量分析法和检查孔出水量测定法检验积水效果，采用P-Q-t曲线分析法，采用注浆量分析法和检孔稳定性分析法对加固效果进行了检验，并对齐岳山隧道F11高压富水断层进行了现场试验和多次注浆循环试验，结果表明，检孔出水量标准为2L/min/m是可行的、可靠的。
Research purposes: The research is done on the examination and evaluation method and standard for the grouting effect under high-pressure and rich-water weak geological condition to provide the reference to working out the criterion and standard for the similar engineering.Research conclusions:The P-Q-t curve analysis method,the analysis method for the yielding water quantity from the bore,the grouting quantity analysis method,the determination of yielding water quantity from the check-up bore,and the check-up bore stability analysis must be used for examining and evaluating the grouting effect to the high-pressure and rich-water fault.The analysis method for the yielding water quantity from the bore and the determination of yielding water quantity from the check-up bore are used for examining the ponding effect.The P-Q-t curve analysis method,the grouting quantity analysis method and the check-up bore stability analysis are used for examining reinforcing effect.The on-site tests and several grouting cycle tests for F11 high-pressure and rich-water fault of Qiyueshan Tunnel show the standard of 2 litres per minute /per meter for the yielding water from the check-up bore is feasible and reliable.
