Conventional casing strength is designed and assessed with safety coefficient method [1,2] by
传统的套管强度设计和评估安全系数法[1,2]的
comparing estimated maximum pressure with minimum casing capacity to obtain a safety coefficient of
比较估计的最大压力最小的套管容量得到安全系数
reliability which, however, is not a method with factors of uncertainty considered. In fact, external loads
可靠性，但是，是不是一个不确定性因素的方法。事实上，外部载荷
and casing strength are uncertain, e.g. due to limited manufacturing techniques and technical inspection,
套管强度是不确定的，例如有限的制造工艺和技术检验，
casing external load, internal pressure, bending moment, temperature and overload are uncertain.
套管外载，内部压力，弯矩，温度和负荷不确定性。
Similarly, different casing manufacturers have different manufacturing techniques and technical standards,
同样，不同厂家有不同的制造技术和技术标准，
therefore, their casings have random mass parameters, such as yield strength, outside diameter, wall
因此，他们的外壳具有随机质量参数，如屈服强度，外径，壁
