Abstract:

Aimed at the lack in traditional analysis method used in soil-cement wall stability, when it is applied to stability analysis of MC composite support structure, a new computing way for anti-overturning stability was developed based on the limit equilibrium theory in combination with the characteristics of MC piles. According to the new method, various factors affected anti-overturning stability of MC piles were analyzed. The results indicate that, C pile is reasonably located in front side of the composite support structure; and the rotation point of overturning is reasonably located above on the end of C pile. Furthermore, the length and width of M pile, length of C pile can be properly increased to enhance the stability of MC piles. Finally, some advices on designing parameters of MC piles are given in terms of the conclusions of analysis and actual experiences in practices.

Key words: MC composite support structure, stability analysis, anti-overturning stability
