【摘要】：滑坡是山區(qū)公路常見的地質災害之一，本文針對國道316線兩當高咀子高填方滑坡的特點，經過實地勘測，科學分析了滑坡形成的主要影響因素，查明了滑坡的類型及成因機理，，提出了三個可行處治方案比選，并對各個方案的合理性、安全性、經濟性進行了詳細的定性、定量分析，提出了以鋼筋混凝土樁板式擋土墻為主，輔以卸載和完善地表排水等相結合的處治滑坡的綜合方案。 本文結合實地勘測資料，對滑塌的原路線做了合理的改線設計，對鋼筋混凝土樁板式擋土墻進行了詳細的結構計算。根據(jù)本工程的特點對滑塌破壞的涵洞采用鋼波紋管涵洞方案重建，對路面結構組成設計，并對建筑材料、施工要求及保通方案做了詳細的設計。 通過工后效果及監(jiān)控測量驗證了鋼筋混凝土樁板墻是處治山區(qū)公路滑坡一種有效的措施，尤其適用于地形受限的回頭曲線高填邊坡的路肩擋墻，或高填邊坡滑塌的地質災害處治。工后效果證明本項目滑坡處治工程設計是成功的。對山區(qū)公路陰濕地帶滑坡及高邊坡垮塌病害處治積累了工程資料。
[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.
