| Abstract: | According to some problems now existed in stability analysis for arch support, the failure mechanism of arch support stability, statistical value of rock parameters, estimation model for limit balance analysis on rigid body, distinguishing creterion for stability safety, etc. are discussed in conbination with engineering examples, such as Ertan Project. The parted safety factor estimation model of limit balance method for rigid body is studied, tested and verified preliminary. |
