| 摘要： | Almost entire work being executed by Border Roads Organisation (BRO) falls in Mountainous or Steep terrain which is characterized by cross slope greater than 25%. Construction of roads in such terrain demands cutting of hill slope and protecting the slope cut by construction of permanent structures in the form of Breast Walls or Retaining Walls. At present, Construction of gravity Retaining walls is the most frequent in the form of Stone masonry (random Ruble Masonry) walls and PCC walls, in BRO. RCC walls are also used for greater heights, However, these types of retaining walls have certain limitations. To overcome these limitations, Reinforced Earth walls shall be used in retaining hill slope. But due to limited space availability behind fascia panel in hill terrain conventional Reinforced Earth walls cannot be used. Therefore, there is need to use combination of anchors drilled into hill slope along with Geo-strip. This type retaining wall known as Hybrid Reinforced Earth Walls, if constructed with proper quality assurance, can overcome above difficulties and have cost benefit also. |
