Abstract

The foundation design of Pengendalian Penduduk dan Keluarga Berencana is located on Jl. R.A. Kartini No. 100, Palu City, Central Sulawesi. In field testing using 2-point of (CPT), the value of hard-ground support at 8 – 9 m below the surface and the loads of building structures of 2 (two) floor buildings that work on the foundations are quite large, this is a consideration in choosing the type of used foundation. The point of this design is to obtain the dimensions of the pile foundation and calculate the bearing capacity of the foundation permit and settlement that meet the safety requirements. The calculation for bearing capacity of the foundation is calculated using (CPT) data and soil shear strength parameter data (c and tetha). Single pile is calculation by using the Semi-Empirical method and using Brooms Method for calculating lateral force on the driven piles. The dimensions of the foundation are planned based on the load (Qv) acting on the entire foundation. Calculation of bearing capacity of a single pile with a penetration depth of 8,20 m and varying dimensions are used in the planning. Based on the calculation of the bearing capacity of a single pile using (CPT) data on the load that works on the foundation, was obtained 25 cm and 30 cm diameter of pile. while the calculation uses ground shear strength parameter data (c and tetha) obtained pile diameter of 30 cm and diameter of 35 cm. Based on the calculation of the bearing capacity of a single pile, the dimensions of the foundation and the settlement in permits has reached the safety requirements.

Abstract

Tawaeli - Toboli is one of the road that often undergo landslide. Most of these roads are in a mountainous area with high steep slopes and poor soil conditions. The road conditions worsened, especially in rainy season resulting the citizen do not know anywhere that is prone to landslides such as in Km 16 to 17. The purpose of this study was to analyze slope stability using bioengineering methods, determine the shear strength of soil without plant roots and soil with plant roots and to determine the potential for landslides that will occur. Bioengineering is used to increase the strength of the soil, and stabilize slopes and reduce erosion on slopes. The slope stability calculation using the Bishop slice method. The calculating of safety factor analyzed using the Slope / W application and manually. Soil samples were taken from 3 (three) points and the soil strength parameters, soil cohesion and friction angle, were obtained through laboratory testing. Tests were carried out using rootless and rooted soil samples. In addition, direct field observations were made to obtain slope angles and slope heights. The results showed that the parameters of soil shear strength, cohesion and friction angle increased with the presence of plant roots. The results of the slope stability analysis show that the conditions of the slope are stable at slope 1 (Km 16) and slope 3 (Km 17) with a safety factor greater than 1.5. While slope 2 (Km 16 +300) has the potential for landslides as a safety factor of less than 1.5. The use of bioengineering increases the safety factor to be greater than 1.5. The calculation of the value of the safety factor using the Slope / W program and the Bishop manual is not much different, but the calculation time with the Slope / W program is faster
