山区公路边坡变形破坏过程机制模拟试验研究

某在建山区高速公路边坡岩性为砂泥岩互层，局部有软弱泥化夹层，边坡存在沿下伏软弱面层面滑动的危险性。通过底面摩擦试验再现此类破坏的发展过程，了解到此类边坡多发生滑移一拉裂破坏，并且了解边坡的破坏范围，有利于边坡的合理加固处治。

Simulation Test Investigation on Slope Deformation Damage Process Mechanism in Mountainous Expressway

The lithological character of slope of some mountainous expressway is the sand shale interbed with weak intercalated clay layer in local part, so the slope is faced with the danger of sliding along the underlying weak surface. This paper reproduces the development process of such damage via the bottom friction test so as to realize the status that the slipping-ripping damage is likely to happen on such slope and to know the range of damage to slope, which are beneficial for the reasonable reinforcing treatment of slope.
