【摘要】 为了进一步分析顺倾岩质高边坡开挖变形机理及变形计算方法,以卸荷岩体力学及弹性力学理论为基础,对顺层岩质边坡开挖前后边坡岩体的力学状态进行了分析,对边坡变形机理及变形计算方法进行了研究.研究结果表明,顺倾岩质边坡在开挖过程中岩体受力状态发生改变,岩体力学参数劣化,造成边坡发生较大变形;顺层岩质边坡变形主要由浅表松弛变形、卸荷回弹变形及顺层滑移变形组成.并以弹性力学为基础提出了边坡卸荷回弹变形的计算方法,依据能量守恒定律推导了顺层滑移变形的计算方法.更多还原

【Abstract】 In order to analyze the deformation mechanism and deformation computing method,based on unloading rock mass mechanics and elastic mechanics,through the slope stress state analyze of initial and unloading,the deformation mechanism and deformation computing method of layered dip rocky slope are studied.The results show that with excavation,the stress state of slope is changed,the mechanic parameters of rock mass is depredated and the deformation is occurred.The deformation types of layered dip rocky slope are relaxation deformation,rebound deformation and slippage deformation.Based on elastic mechanics,the rebound deformation calculation method is proposed.According to law of conservation of energy,the slippage deformation calculation method is proposed.更多还原
