摘　　要：耐久性与允许渗漏量是工程防水的关键指标,工程中一般以简化的分级方式表达成防水等级。这些指标均存在目标与结果属性,采用系统工程理论进行辨析,所建立的工程防水关键指标体系显示:工程防水等级的实质是可靠度;依据应用场景与影响因素可制定耐久性与渗漏量目标,工程防水的实际性能需结合影响因素进行验证;采用防水可靠度指标可将工程防水的目标与结果形成关联,并实现量化判定。由此,防水系统、应用场景、影响因素可统一成完整体系。Durability and allowable leakage are the key indicators of engineering waterproofing.In engineering,it is generally expressed as waterproofing grade in a simplified grading way.These indicators have target and result attributes.The key index system of engineering waterproofing is established by using system engineering theory.The key index system of engineering waterproofing shows that the essence of engineering waterproofing grade is reliability.According to the application scenarios and influencing factors,the durability and leakage targets can be formulated,and the actual performance of engineering waterproofing needs to be verified in combination with the influencing factors.The waterproof reliability index can be used to correlate the target and result of engineering waterproof,and realize quantitative judgment.Therefore,the waterproof system,application scenarios and influencing factors can be unified into a complete system.
