可靠概率 meaning in Chinese

probability of survival

4 . the seismic dynamic reliabilities of the nanjing changjiang tunnel were analyzed , and its dynamic reliable and disable probabilities under the 7 degree earthquake were obtained , by using the maximum stochastic responses and the first overstress mechanism . in the other hand , the probability of serious seismic intensity and its probability distribution function were calculated by analyzing the seismic degree , and the seismic dynamic reliable and disable probabilities of the tunnel in its design reference period were calculated by using the maximum stochastic responses and the first overstress mechanism
4采用最大随机地震响应和首超破坏理论分析了隧道抗震动力可靠度，得到了隧道在七度地震作用下的地震动力可靠概率和失效概率；并通过对南京长江隧址的地震危险性分析，得到了各烈度地震的发生概率及其概率分布函数，在此基础上，分别采用最大响应和首超破坏理论计算了隧道在设计基准期内的安全概率和失效概率。
