摘要
山体滑坡是影响高速公路正常运营的主要问题之一。针对上述问题将基于吕梁高速公路处的地貌特征为基础,利用极限平衡原理探索分析高速公路边坡的稳定特性。研究结果表明,吕梁山地区高速公路所处的土质边坡安全系数相对较低,当出现降雨或积雪等问题时,边坡内部水作用力增大从而降低了边坡的安全系数,同时边坡的软弱带及可能发生的滑坡量均会发生改变。
Landslide is one of the main problems affecting the normal operation of motorways.In view of the above problems,based on the geomorphic characteristics of Lvliang motorways,the stability characteristics of motorways slope are explored and analyzed by using the principle of limit equilibrium.It shows that the safety factor of the soil slope in Lvliang mountain area is relatively low.When there are phenomenon such as rainfall or snow,it results the internal water force of the slope increases and reduces the safety factor of the slope.At the same time,the soft zone of the slope and the amount of possible landslide will change.
