Abstract

Road settlement often occurs because that soil cannot accommodate the load capacity. Therefore, the study to analysis of lightweight concrete “cakar ayam” foundation was conducted. The idea of “cakar Ayam” concept was introduced by Prof. Dr. Ir. Sediyatmo. Objective of these studies was achieved which is to determine the settlement value of lightweight concrete “Cakar Ayam” foundation design on soft clay, sand, clayey silt under the different loads. Hence, the effectiveness of lightweight concrete “cakar ayam” foundation on that soil, have been able to determined according the settlement value was obtained. Implementation of research was doing using Plaxis 3D foundation software. The foundation design was various according to the several of the column length. The slab thickness, spacing between column, foundation and column size was fixed. Soil parameters to analyse lightweight concrete “cakar ayam” foundation, was obtained from previous studies and Research Center of Soft Soil, Universiti Tun Hussien Onn Malaysia, (RECESS, UTHM). Each design was tested by different loads to get the settlement value. From the results show, the settlements value was obtained show concept of “cakar ayam” foundation, not effective to be implement on soft clay. The settlement value was over 25 mm, when the load 20 kN/m2 was applied on the foundation, to all length of column on soft clay. However, the settlement value was lower than 25 mm, when the load 40 kN/m2 was applied on the foundation, to all length of column on sand and clayey silt. From all the settlement value, it could be seen that clayey silt result was more effective than sand. The settlement value also was decrease when the length of pile was increase. In conclusion, the objective of the study was achieved.
