| 中文摘要: |
| 边坡稳定是公路工程建设中的热点问题。为消除津围公路北二线K4段由于边坡失稳产生滑坡等地质灾害隐患,对边坡所处的地形地貌、地层岩性、地质构造、裂隙及水文地质条件进行系统分析,进行边坡稳定性工程地质评价。研究结果表明,工作区属构造侵蚀中低山沟谷斜坡地貌,断层穿过工程线路,地表松散人工填土层工程地质条件较差,坡洪积层与残坡积层工程地质条件较好,硬的基岩工程地质条件较好,软弱基岩进水后软化膨胀,极易形成滑坡的滑动面。综合分析边坡坡向、坡脚、地层产状、节理四个要素,建议基岩层理与节理相交区域实施重点加固。南侧断层带建议设计时按复杂土层边坡确定其稳定性,并采取针对性加固措施。研究成果及措施可为同类地质调查工程工作提供借鉴。 |

| Slop stability is a hot issues in the construction of highway engineering. To eliminate geological disasters such as landslide slope unstability hidden trouble at K4 section in the north second line of Jinwei highway, the landform, stratum lithology, geological structure, fracture and hydrogeological conditions of slope are analyzized and the engineering geology of the slope stability is evaluated. The research results show that the job belongs to low mountain gully slope tectonic erosion landform, fault lines through the engineering, surface loose artificial filling soil engineering geological conditions is poorer, slope diluvium and residual diluvial layer engineering geological condition is good, soft bedrock water softening after inflation, easy to form a landslide slip surface. Based on the comprehensive analysis of slope direction, slope foot, formation occurrence and joint, it is suggested to reinforce the intersection area of bedrock bedding and joint. It is suggested that that the southern fault zone should be designed to determine the stability of the complex soil slop and take targeted reinforcement measures. |
