Abstract

This study aims to determine the material composition and dimensions of X-block, develop a slope reinforcement model using X-block, evaluate the mechanical behavior of slopes that are reinforced with rock-bound by X-block, and analyze the performance of slope reinforcement using X-block. This research was conducted at Hasanuddin University's soil mechanics and civil engineering structure laboratory. The model scale test was employed in this study. The geometrical speciation of the test box is 150 cm in length, 60 cm in width, and 100 cm in height. The X-block model was produced using concrete with a FC of 25 MPa. The X-block was divided into two types: X-block type 1 and X-block type 2. Tensile strength testing is performed on the X-block. The slopes are made of clay soil and have a slope angle of 70 degrees. The loading test was conducted in three stages: without block, with X-block type 1, and with X-block type 2. The loading test uses a hydraulic pump equipped with a load cell and LVDT. The tensile strength of X-block type 1 is 2.56 MPa, whereas X-block type 2 has a tensile strength of 4.35 MPa. The development of the type X-block design, which is used as a retaining wall material, has shown that it can effectively withstand landslides on the slopes under consideration. The slope safety factor rose dramatically after being reinforced with type X-blocks, reaching 2.73 for both X-block type 1 and X-block type 2. Doi: 10.28991/CEJ-2022-08-03-014 Full Text: PDF

Highlights

Landslides inflict significant damage and occur in a variety of locations across the world [1]
The material applied to set up the slopes is a soft soil type acquired from landslide-prone locations
This avalanche falls within the category of rapid avalanche

Summary

Introduction

Landslides inflict significant damage and occur in a variety of locations across the world [1]. Landslides can occur as a result of erosion on the surface of a slope. Slope failure can be caused by land subsidence, in areas prone to settlement, such as clay soil [6]. Plant medium or vegetative approaches have been used to manage slope surface erosion. The carrying capacity of the subgrade is the key issue for infrastructure construction in soft clay soils, since the subgrade compaction is rather substantial, implying that it will endure longer. This issue can be rectified by strengthening the soil to make it stronger [7, 8]
