川藏公路拉月滑坡的块状破坏特征

Rock Lump of Landslide of Layue Destruction Feature Analysis in Sichuan Xizhang Highway

拉月滑坡位于东久河左岸 ,为典型的高位岩质滑坡。 1967- 0 8- 2 9拉月一带山体突然发生特大型滑坡 ,体积超过千万立方米 ,是川藏公路线上著名的“拉月大塌方”灾害。文章应用块状岩体稳定性分析方法 ,对同结构岩石块体相互嵌合、形成具不同稳定状况的的岩体结构、控制了滑坡的发生的特点进行了分析 ,证明该方法判别岩质滑坡的稳定性是非常有效的。岩质滑坡在西藏与西南地区都十分普遍 ,因此 ,通过对拉月滑坡块状破坏过程的分析 ,对其它岩质滑坡的稳定性判别具有很好的借鉴作用。

Landslide of layue locates in left bank of Dongjiou r iver It's typical rock landslide for the high position On August 29,1967,Lay ue mountain body occur suddenly big type to go down, that volume ten million cu bic Landslide of Layue is famous calamity in Sichuan-Xizhang Highway The paper used rock mass stability analysis method To analyzing different structural roc k mass inlaid mutually,and formed different stability rock mass structure,and controlled landslide characteristic It had been proved that analysis method of rock mass stability was very effective Rock landslide is very universal in Tibe t and southwest area Therefore,To analyzing rock mass destroying for landslide of Layue, it has good affecting for other rock landslide
