Rapid construction of buildings in urban area is creating lack of space available for new construction. This problem enforced to construct building on slope in hilly regions. However, the engineers and designers are concerned with the stability analysis of structures built on soil slopes, as it is difficult to achieve a uniform structural level on mountainous terrain. Also, it cannot be reduced to the same level of structural forms and part of base member may not be bound by an identical horizontal plane. The fundamental stability of the structure built on hill slope depends upon on its slope stability. Slope failure has been identified as one of the frequent devastating natural disasters that have claimed huge loss of property and lives. Therefore, in this research, “Phase 2 (2002)”, a Rocscience Finite Element (FE) program and “Slide”, a Rocscience limit equilibrium program were used to simulate and analyze a complex multi-staged model with RCC pile, Anchor Bolt and Geogrid for the stability analysis of slope. Bishop’s method was used to evaluate and analyze the factor of safety. Analysis of the two section (Section 1-1 and 2-2) of slope was taken into consideration for slope stability analysis. As per the analysis using the limit equilibrium approach, the factor of safety for existing slope at Section 1-1 and Section 1-1 was found to be 0.579 and 0.70 respectively. Moreover, it was found that the factor of safety of slope was increased significantly from 0.579 to 1.593 in Sections 1-1 and 0.70 to 1.319 in Section 2-2. In addition, the factor of safety of slope with strength reduction method is 1.408 and 1.05 for Sections 1 and 2 respectively after slope stabilization work in seismic condition. This shows that, the construction of buildings in slope terrain is possible, but it needs specialized excavation and slope protection work. RCC pile with anchor bolt and geogrid is one of the sustainable solutions for construction of structure in slope area.

碾压混凝土桩、锚杆、土工格栅在不稳定边坡建筑施工中的应用

城市地区建筑物的快速建设造成了可用于新建筑的空间不足。这个问题迫使在丘陵地区的斜坡上建造建筑物。然而，工程师和设计师关注的是土质边坡结构的稳定性分析，因为在山地地形上很难实现统一的结构水平。也不能降为同级结构形式，部分基础构件不得受同一水平面约束。建在山坡上的建筑物的基本稳定性取决于其边坡稳定性。斜坡崩塌已被确定为频繁发生的破坏性自然灾害之一，已造成巨大的财产和生命损失。因此，在这项研究中，“Phase 2 (2002)”，一个 Rocscience 有限元 (FE) 程序和“Slide”，一个 Rocscience 极限平衡程序被用来模拟和分析一个复杂的多阶段模型与 RCC 桩、锚杆和土工格栅的边坡稳定性分析。采用Bishop法对安全系数进行评价分析。边坡稳定性分析考虑了边坡的两个部分（第 1-1 和 2-2 部分）的分析。根据极限平衡法分析，1-1 段和 1-1 段既有边坡的安全系数分别为 0.579 和 0.70。此外，还发现边坡安全系数在 1-1 段从 0.579 显着增加到 1.593，在 2-2 段从 0.70 显着增加到 1.319。另外，采用强度折减法的边坡安全系数为1.408和1。05 分别用于第 1 部分和第 2 部分在地震条件下进行边坡加固工作后。这说明，在坡地地形上建造建筑物是可行的，但需要专门的开挖和护坡工作。锚杆加土工格栅碾压混凝土桩是边坡地区结构施工的可持续解决方案之一。
