Landslide disasters are often a threat to the smooth transportation and economy of the community. Meulaboh-Geumpang crossroad, located in the western coastal region of Aceh Province, is one of the landslides-prone areas. Thus, the appropriate solution is necessary for preventing and handling the landslides in this area. This study conducted slope reinforcement using segmental concrete blocks combined with geogrids. The planned vertical distance of the geogrid (Sv) was 0.2 m, 0.4 m, and 0.6 m, while the length of the geogrid plan was 1 meter outside the failure envelope of the slip surface at the existing condition. The slope of the planned slope angle for the installation of the concrete blocks was 45, 60, and 90. The dimensions of segmental concrete blocks were 20 cm high, 30 cm wide, and 40 cm long. The safety factor, at the condition after overall reinforcement, reached an acceptable amount for handling, only at STA 84 + 280 with a slope of 90. A reinforced concrete beam was not added to the foot of segmental concrete blocks because it did not meet the acceptable safety factor, which was 1.32. The result of this analysis is to provide useful information about the form of a landslide that occurred. It will also inform the best combination of concrete block wall reinforced with geogrid for the reinforcement on the slopes. Thus, relevant parties can use it for landslide handling in these locations.

Meulaboh-Geumpang道路分段混凝土砌块墙和土工格栅的边坡稳定性分析

山体滑坡灾害往往对社区的顺利交通和经济构成威胁。Meulaboh-Geumpang十字路口位于亚齐省西部沿海地区,是山体滑坡多发地区之一。因此,需要适当的解决方案来预防和处理该地区的滑坡。本研究采用分段混凝土砌块结合土工格栅进行边坡加固。土工格栅的规划垂直距离(Sv)分别为0.2 m、0.4 m和0.6 m,而土工格栅的规划长度在现有条件下滑移面破坏包络线外1米。安装混凝土砌块的计划坡度角为45、60和90。节段混凝土砌块的尺寸为高20厘米,宽30厘米,长40厘米。安全系数,在整体加固后的条件下,达到可接受的搬运量,仅在 STA 84 + 280 坡度为 90。钢筋混凝土梁未添加到节段混凝土块的脚部,因为它不符合可接受的安全系数,这是1.32。该分析的结果是提供有关发生的滑坡形式的有用信息。它还将告知用土工格栅加固的混凝土砌块墙的最佳组合,以在斜坡上进行加固。因此,相关方可以将其用于这些地点的滑坡处理。该分析的结果是提供有关发生的滑坡形式的有用信息。它还将告知用土工格栅加固的混凝土砌块墙的最佳组合,以在斜坡上进行加固。因此,相关方可以将其用于这些地点的滑坡处理。该分析的结果是提供有关发生的滑坡形式的有用信息。它还将告知用土工格栅加固的混凝土砌块墙的最佳组合,以在斜坡上进行加固。因此,相关方可以将其用于这些地点的滑坡处理。
