摘　　要：屋面工程防水耐久性是一定时间内受影响因素作用屋面维持允许渗漏量的能力,由于影响因素与衰减机理的复杂性,防水耐久性需结合经验和量化方法判定。通过“半经验、半概率”因子计算方法对SBS改性沥青防水卷材屋面的耐久性进行预测、分析,参照工作年限是耐久性判定的基准,也是最关键的部分。因子取值需谨慎,尽量减少修正因子类别。由于不确定因素的存在,耐久性适合采用分布特征、置信区间进行表达。The waterproof durability of roof engineering refers to the ability of the roof to maintain the allowable leakage rate within a certain period of time under the influence of influencing factors.Due to the complexity of influencing factors and attenuation mechanisms,the waterproof durability needs to be judged based on experience and quantitative methods.The durability of SBS modified asphalt waterproofing membrane roofs is predicted and analyzed using the“semi experience,semi probability”factor calculation method.The reference service life is the benchmark for durability judgment and the most critical part;The factor values should be taken with caution and the categories of correction factors should be minimized as much as possible;Due to the presence of uncertain factors,durability is suitable to be expressed using distribution characteristics and confidence intervals.
