摘要
针对东北地区部分输电线路杆塔基础地表由1.5~2.5 m厚粘土层覆盖,以下为岩层,且岩体整体性好,风化程度轻的地质情况,指出如采用掏挖基础、岩石锚杆基础等大开挖型式,易造成环境植被大面积破坏并加大基础工程量。通过总结分析掏挖基础和岩石基础的优点,提出了一种适宜这种地质条件且经济环保的掏挖加岩石锚杆复合环保型原状土基础,实际输电线路的应用验证了该种基础的可行性。
The surface of transmission pole tower foundation in Northeast China is covered by clay layer with the depth of 1.5～2.5 m,under which is rocky layer with sound comprehensive properties and slightly weathered conditions.Large scale digging methods,such as digging foundation and rock anchor rod foundation may destroy large area of vegetation and increase construction quantity.A compound foundation which keeps the original foundation type and is suitable for construction in this geological condition,digging foundation plus rock anchor rod foundation,has been proposed based on the summary of advantages of digging foundation and rock anchor rod foundation.The practical application of transmission line verified the feasibility of this type of foundation.
