| 摘 要： | 结合某大桥桥基岸坡地质条件,采用相似原理为基础的底摩擦试验方法,定性模拟分析了在天然状态和加载条件下岸坡岩体的变形破坏过程和模式。试验结果表明:在天然状态下,左右岸岸坡岩体处于稳定状态;在加载条件下,左岸岸坡岩体稳定,右岸发育的错落体失稳,而导致整个岸坡不稳定,建议对其进行预加固或改变桥墩位置。

| Abstract: | Combined with engineering geological conditions of bridge foundation slope,deformation and failure process on the condition of natural state and loading is simulated and analyzed by floor-friction test method based on similarity principle qualitatively.The test results indicate that the rock masses of slopes at left and right banks are in stable state under the condition of natural state;under the condition of loading rock mass in left bank is in stable state;but the scattered earth-body in right bank is un... |
