Safety evaluation to arch dam couldn’t meet the need of project according existing method at present. In this paper, the collapse probability is given through cracking trajectory to evaluate the safety of dam, and overload coefficients are also compared.
拱坝的整体安全评价是工程上极为关注并且目前还未很好解决的一个问题，本文利用破坏追踪提出溃坝概率的概念，对拱坝的整体安全性进行评价，得到拱坝破坏到任意程度的概率、当时破坏的难易程度和溃坝过程，并与超载实验进行了比较。

这对于追踪您的进程朝向覆盖率数据目标的情况，以及发现覆盖率的破坏非常有用。
They are useful for tracking your progress toward coverage goals, and for detecting coverage erosion.
一个工作区并没有包含其上级内容的拷贝：如果它包含了，那么对象必须拥有独一无二的GUIDs，而这又将破坏轻松追踪的功能。
A Workspace does not contain a copy of its parent content: if it did, then the objects would have to have unique GUIDs, and this would destroy the capability of easy tracing.
系统方法也被大范围应用在追踪商业循环中，比如在斯普林斯丁森开拓性的破坏性技术上。
Thesystems approach is also widely used to track business cycles, as in theground-breaking work of Clayton Christensen on disruptive technologies.
