发布时间：2019-01-19 10:26
【摘要】：滑坡是山区公路常见的地质灾害之一，本文针对国道316线两当高咀子高填方滑坡的特点，经过实地勘测，科学分析了滑坡形成的主要影响因素，查明了滑坡的类型及成因机理，，提出了三个可行处治方案比选，并对各个方案的合理性、安全性、经济性进行了详细的定性、定量分析，提出了以钢筋混凝土桩板式挡土墙为主，辅以卸载和完善地表排水等相结合的处治滑坡的综合方案。 本文结合实地勘测资料，对滑塌的原路线做了合理的改线设计，对钢筋混凝土桩板式挡土墙进行了详细的结构计算。根据本工程的特点对滑塌破坏的涵洞采用钢波纹管涵洞方案重建，对路面结构组成设计，并对建筑材料、施工要求及保通方案做了详细的设计。 通过工后效果及监控测量验证了钢筋混凝土桩板墙是处治山区公路滑坡一种有效的措施，尤其适用于地形受限的回头曲线高填边坡的路肩挡墙，或高填边坡滑塌的地质灾害处治。工后效果证明本项目滑坡处治工程设计是成功的。对山区公路阴湿地带滑坡及高边坡垮塌病害处治积累了工程资料。
[Abstract]:Landslide is one of the common geological disasters in mountainous area. According to the characteristics of the landslide in Liangdang Gaozui high fill area of National Highway 316, the main influencing factors of landslide formation are scientifically analyzed, and the types and formation mechanism of landslide are found out. The comparison and selection of three feasible treatment schemes are put forward. The rationality, safety and economy of each scheme are analyzed qualitatively and quantitatively, and the reinforced concrete pile-slab retaining wall is put forward. Combined with unloading and improving surface drainage, a comprehensive scheme for landslide treatment is proposed. Based on the field survey data, this paper makes a reasonable route modification design for the original route of the slide, and makes a detailed structural calculation of the reinforced concrete pile-slab retaining wall. According to the characteristics of this project, steel corrugated pipe culvert scheme is adopted to reconstruct the culvert, and the pavement structure composition is designed, and the building materials, construction requirements and guarantee scheme are designed in detail. It is proved that reinforced concrete pile-slab wall is an effective measure to treat highway landslide in mountainous area through post-work effect and monitoring and measurement, especially suitable for the shoulder retaining wall of high fill slope with reversion curve, which is limited by terrain. Or high fill slope landslide geological disaster treatment. The effect after work proved that the project landslide treatment engineering design is successful. The engineering data are accumulated for the treatment of landslide and high slope collapse in mountainous highway.
