Researching On The Disturbed Zone For Cutting Bedding High Rock Slope & Calculation Method Of Micro-pile

Conclusions of the paper mainly include the determination of the disturbed zone for cutting bedding high rock slope and calculation method of micro-pile.Some stabilizing structures must be set before cutting a bedding high rock slope, and how to determinate the range of disturbed zone becomes the key problem.The study background is high rock slope projects in the expressway project from Wanzhou to Liangping in Chongqing city. The paper makes a summary of the mechanical and physical properties of the disturbed zone, at the same time, making an analysis for factors which have effects on the disturbed zone. On the basis of the slope geological structure, three typical slopes geological structures are selected to be statistically analyzed .The disturbed zone can also be achieved with the numerical analysis method, and it is interpreted in detail by an example.Compared with ordinary anti-slide piles, the micro-pile is a kind of pile with a smaller caliber. As a kind of new style stabilizing structure, it has many advantages over other structures, just as faster construction process, lower costs and so on. Firstly, the paper sets forth some ordinary problems in actual projects; secondly, it pays more attention to seeking a reasonable calculation method of the inner force of micro-pile. To some degree, these study conclusions are of both new theoretical significance and good economic and social significance.
