Early study of slope strength modeling of block type x

Abstract

Abstract The development of slope strengthening forms requires innovative efforts. One way is to make a particular prototype or model by performing laboratory-scale testing. Slope failure with the use of the riprap method is still frequent; therefore, it needs to be supported by a block to maximize this riprap method. This research is a preliminary study in making the type x block model a form of slope reinforcement. This study has three types of material: clay as slope making material, crushed stone as riprap, and concrete for making type x blocks. This study aims to determine the index value of the soil properties used as slope-making material and to measure the value of the x-block type tensile strength test. The soil properties index shows that this soil is clay with a plasticity index of 10.51%, clay content 42.79%, Friction Angle (φ) of 23.24°, and Specific Gravity (Gs) of 2.728. Whereas the tensile strength test results of 4 type x blocks, namely type x brace 1, type x locked 1, type x brace two, and type x closed 2, are 0.293 MPa, 0.128 MPa, 0.205 MPa, and 0.128 MPa, respectively. The test results show that the Block x brace model’s tensile strength is greater than the locked Block X model.
