顺层边坡岩体结构稳定性位移理论
DISPLACEMENT THEORY OF STRUCTURE STABILITY FOR ROCK MASS BEDDING SLOPE
【摘要】 岩体顺层边坡的破坏主要表现为溃屈和剪切滑动。通过对顺层边坡岩体结构屈曲和后屈曲变形因素的分析 ,提出了以位移形式表示的层状边坡溃屈破坏的上限值。根据边坡岩体渐进性破坏的机理得出了不同情况下边坡岩体剪切滑动破坏的极限长度 ,给出了顺层边坡岩体结构的稳定性位移判据
【Abstract】 The failures of rock mass bedding slopes mainly display the buckling and the shearing slip. The upper bound for buckling failure of bedding slope is derived in the form of displacement by researching buckling deformation factors. According to the mechanism of progressive failure for rock mass bedding slope, the ultimate length of the slope failures with shearing slip is derived in different cases. The displacement criteria of rock structure stability are given for bedding rock slope.
