Abstract

The size of the reliability index can reflect the stability of excavation. This paper analyzes the engineering structure that is derived the reliability index, and the engineering model of structural reliability methods. The different types of supporting structure are taken into account, including the additional load, earth pressure, a variety of loads, the analysis of the main failure mode of instability as well as the establishment of the supporting structure on different limit state equations. Thus, it can establish the structure-based engineering and the reliability analysis on the reliability models.
