    ESTIMATION AND CONTROLLING OF EXCAVATION WALL DEFORMATION USING ELASTO-PLASTIC CALCULATION WITH NONLINEAR GROUND CONSIDERATIONS
    (International Journal of Psychosocial Rehabilitation, Vol. 24, Issue 2, 2020) Agustian, Yanyan; Setiawan, Asep; AshSiddiq, Raden Herdian Bayu
    In the excavation work, the calculation of lateral pressure is very important, because it concerns the safety and smoothness of construction work. In fact, in the field the calculation of the movement of the retaining wall is very complex. This is because the soil has mechanical properties that are not linear, so it requires calculation in other ways, which also takes into account the nonlinearity of the soil and the spring properties of the soil and retaining wall itself. In the case study of this paper outlines the calculation of the nature of the soil and the retaining wall in order to estimate and evaluate the movement of the retaining wall during excavation work. The results of calculations show there is a good correlation between the results of calculations and the results of monitoring the movement in the field. So that this method can be used for similar calculations in excavation works.

    LATERAL DEFORMATION ESTIMATION ON DEEP EXCAVATION BY USING ELASTO-PLASTIC CALCULATION
    (Solid State Technology Volume: 63 Issue: 3, 2020) Agustian, Yanyan; Setiawan, Asep; AshSiddiq, Raden Herdian Bayu
    For safety and smoothness of excavation work, especially deep excavation, it is necessary to calculate the horizontal displacement of the soil wall so that its movement can be controlled. This must be done continuously during the excavation process until the backfilling process is complete. However, the calculation of ground motion due to the lateral forces of the soil is very complex. This is due to the nonlinear nature of the soil, by means that the calculation must consider the nonlinearity of the soil and also consider the properties of the soil spring and the retaining wall itself. One computational approach has been undertaken in this case study which describes the calculation of soil properties and retaining walls to estimate and evaluate the movement of the retaining walls during excavation works. The results of the calculations show a good correlation between the results of the calculations and the results of monitoring the movements in the field. So that this method can be used for similar calculations in excavation work.
