| 摘 要： | 红层地层在我国分布广泛,红层软岩土是一种特殊岩土,其颗粒易破碎,强度低,遇水后易崩解与软化,其工程性质很难满足站场路堤填料要求。该文结合站场填方工程实例,针对采用红层软岩土这一特殊填料的高填方边坡,通过数值模拟对不同压实度下其填方区竖向位移、边坡水平位移以及应力状态进行分析,以确定合适的填筑压实度;同时,对填筑边坡的稳定性进行分析,提出了填筑边坡可能存在的最不利滑面位置。

Analysis On Deformation Characteristics of High Filled Slope of Red-Bed Soft Rock |

| Abstract: | Red beds, a special terrane with low strength, vulnerable to disintegration and soitening by water, is widely seen in China. Its engineering characteristics can hardly meet the requirements of filler for station yard and embankment. Based on engineering practice of station yard filling with red-bed soft rock used as the special filling material to make high filled slope, vertical displacement of fill section, horizontal displacement of slope and stress state under different compaction degrees are analyzed through numerical simulation. Stability of filled slope is also analyzed with potential slip surface of filled slope presented. |
