1977年由于滑坡滑向建筑场地和部分地冲向河谷,破坏了近3百万方岩体,堆满了所有清基面和基坑。岩体缓慢的运动至到其剧烈地滑动,延续了很长的时间(引起滑动可能是前夕的暴雨),实际上在滑过后立刻在该岩体的低部形成了平台。滑坡体本身是坡积物堆积,复盖于黑色粘土层上面,其接触面即为滑动面。 As a result of landslides sliding into the construction site and partly into the valley in 1977, nearly 3 million cubic meters of rock mass were destroyed, filling all the clear basins and foundations. The slow movement of the rock mass until it lapped violently for a long time (causing slippage to be an eruptive rainstorm on the eve), actually formed a platform on the lower part of the rock mass immediately after slippage. Landslide itself is the accumulation of slope accumulation, covered in black clay layer, the contact surface is the sliding surface.
