查询词典 failure analysis

Using FEM, the coupled action of thermal stress and crustal stress has been taken into account. The regularities of distribution of the horizontal displacement of surface of slope and the shear stress of junction plane between shotcrete and rock are discussed too. According to the analysis, under the combined action of thermal stress and crustal stress, top and foot of slope are liable to be destructed. Ordinary, the destructional form of the top is tensile failure and the bottom is shear failure. There are some time effect of displacement and stress in the surface of slope and distribution of temperature in slope, which agrees with actual measured rules.

采用有限元的方法，考虑地应力与温度应力的耦合作用，分析了在一定的边界温度作用下不同时刻边坡喷层面的水平位移，以及喷层与岩层结合面处的剪应力的分布规律；指出在温度应力与地应力的共同作用下，喷混凝土边坡坡顶与坡脚均为容易发生破坏的地方，通常坡顶的破坏型式为拉张破坏而坡脚则为剪切破坏；边坡内的温度分布、边坡表面的位移与应力的变化均存在一定的时间效应，这一规律与实测规律比较吻合。

From the analysis, we can conclude that at least three aspects will cause cross-cultural pragmatic failure: a. The intersection of pragmeme subset A and pragmeme subset B is an empty set; b. Interlocutor A's pattern of pract elements coupling is different from that of interlocutor B's; c. The outranging of allopract causes the transferring from a pragmeme to another pragmeme. The three aspects of pragmeme theory enrich the studies on cross-cultural pragmatic failure.

通过分析，我们得出跨文化语用失误的原因有三：第一，交际者双方对于某一语用行为的语用位交集为空集时会导致跨文化语用失误；第二，交际者双方选择的语用素集合中元素之间耦合方式不相同时会导致跨文化语用失误；第三，交际者一方的语用变体超出对方语用位范畴时会导致跨文化语用失误。

Moreover, this article offers various improvement programs for smoke evacuation system in subways system. Initially, we offer an idea to minimize the anti-smoke divisions and to rearrange vent positions to resolve the failure of station smoke evacuation mode. In the study of smoke evacuation process at tunnel track area, we find an upward slope will block smoke evacuation. This study also finds that start of fans operation will speed up the accumulation of smoke and endanger people's life during escape. The way to resolve is that we need to add fans at upward slope. This result is different from the report of one dimensional SES simulate analysis. To timely correct the safety evaluation result in SES report and to efficiently improve the failure of smoke evacuation system design are recommended by this article. Therefore, an increase of time for people to escape in fire hazard with less casualty.

本文另於对捷运排烟系统提出各项改善方案中，初步提出车站排烟系统防烟区划缩小构想，并配合风口位置调整策略来解决失效的车站排烟模式；而隧道轨道区排烟系统在研究过程发现爬坡段有阻碍排烟效果，本研究发现风机开启后反而加速烟气滞留并危害人员逃生，解决之道则必需於爬坡段增加风机来排除，此与一维式SES模拟分析报告结果不同，故能藉以及时更正SES报告之安全评估结果，经由所提改善方案，有效改善所发现排烟系统设计之失效，提高人员火灾时逃生的安全时间，降低人员伤亡。
