随着社会和技术水平的发展,土木工程中结构更趋于复杂,如何更安全的保证结构的可靠安全,成为当前亟待解决重要议题之一。在土木工程中要以结构可靠度作为理论基础,对工程建设过程中引发问题的不确定因素进行预测和防范。本文介绍了土木工程中的可靠度的理论在我国的发展现状,并简要介绍了可靠度理论中两种常用的方法,以此,尽量减少结构的不确定性对结构设计的影响,取得更好的社会效益。 With the development of society and technology, the structure in civil engineering tends to be more complicated. How to ensure the safety and reliability of structures more safely has become one of the most important issues to be solved urgently. In civil engineering, structural reliability should be taken as the theoretical basis to predict and prevent the uncertain factors that cause problems in the construction process. This paper introduces the current status of the theory of reliability in civil engineering in China and briefly introduces two commonly used methods in reliability theory to minimize the impact of structural uncertainty on structural design and achieve better results Social benefits
