摘要
建立了一套完整的岩体注浆堵水可靠性设计系统 ,绘制了注浆堵水故障树及成功树 ,建立了各基本事件的极限状态方程 ,提出了关于对单孔的初注、复注、辅注及多孔系统的各种注浆逻辑关系计算模型及其可靠度计算方法 ,定义了注浆系统的工作状态及不同注浆工程的安全等级 ,给出了各种注浆工程的可靠性指标 ,给出了注浆工程的可靠性设计方法及步骤。可用于指导现场注浆工程的设计和施工 ,具有较大的理论意义和广阔的应用前景。
A complete system of reliability design of grouting for stopping water in rock mass was established in this paper. Fault tree of grouting for stopping water and simplified successful tree were drawn. Limit state equation of basic events were found. Calculation models of logical relation and calculation methods of reliability for first grouting, repetitive grouting, auxiliary grouting of single hole and multiple hole grouting system were established. Working states and security grades of grouting system were defined. Reliability indexes of different grouting projects were given. Reliability design method and process of grouting were given. It can instruct design and construction of grouting projects in site, and has important theoretical value and wide application prospects.
