Abstract

Bearing capacity of the soil and the foundation has a close link with the level of safety to the occupants of a building. A foundation design said to be true if the load transmitted by the foundation to the ground does not exceed the power of the land concerned.If the soil strength is exceeded, then a decrease (settlement) excessive or collapse of land will occur, causing damage to the construction which is above the foundation. This research aimsto obtain the value of the soil bearing capacity of shallow foundations in several areas of Aceh Besar, and used as a mapping using ArcGIS 9.2 software. Secondary data used is Cone Penetration Test (CPT) ere obtained from the Laboratory of Soil Mechanics Faculty of Engineering, University of Syiah Kuala. Number of points CPT or sondir is 34 points.  Furthermore, to determine the location of these points in the field using GPS (Global Positioning System). The result shows that most of the area in the study area has a bearing capacity of the land is permitted 50 ton / m2. The area has bearing capacity permits between 50 ton/m2 to 100 ton/m2 occupied area Siem, Cot Gue, Bilui, Adjunct, Baet, Mon Ikeun,Lamkruet, and Lhoknga. Furthermore, the results of the bearing capacity of land used as a mapping so that it becomes a reference in planning the foundation of a building or otherinfrastructure in the region of Aceh Besar.

Abstract

This research aims to evaluate effect of soil plasticity index (PI) to shear strength parameters, e.i. the angle of shearing (φ) and cohesion value (c). Parameters of φ and c obtained from Direct Shear Test in soil mechanics laboratory. The soil samples used for the research were taken from Neuheun Village, Mesjid Raya Subdistrict, and Aceh Besar District. Based on AASHTO soil classification, the soil sample is a Group A-7-6, whereas based on USCS soil classification, the soil is sandy clay of CL symbol. Soil specimen for Undisturbed Sample (UDS) and Disturbed Sample (DS) were 20 samples respectively, each sample was made to be three sub samples. The result of research shows that there is a linier correlation of shearing angle to PI, i.e., φ = -0,700 IP + 47,474, R2 = 0.882 for Undisturbed Samples (UDS) and φ = -1,757 IP + 59,313, R2 = 0.891 for Disturbed Samples (DS). The result of research also shows there is a linier correlation of cohesion value to PI, i.e., c = -0,053 IP + 1,569, R2 = 0.887 for UDS and c = -0,076 IP + 1,882, R2 = 0.783 for DS. It can be concluded that shear strength parameters for all tested samples in this research influenced by soil plasticity index. The higher soil plasticity index resulted the lower Shear Strength Parameters.

Abstract

Roads Blangkejeren - Laweaunan is a one-lane road transport in the Province ofNanggroe Aceh Darussalam, which has an altitude slopes varying between 3.5 to 4.3 m. Earthquakes, rainfall and altitude slopes greatly affect the stability of the slopes on theseroads. The stability analysis aims to obtain a slope stability conditions that meet safety requirements at Jalan Blangkejeren - Laweaunan Gayo Lues District of Nanggroe Aceh Darussalam. Slope stability design using the simplified Bishop method and Plaxissoftware. The use of these methods has given the ease and accuracy in solving the problem of stability of the slope to meet the security requirements of slope stability. Based on the analysis of the simplified Bishop method and Plaxis at Jalan Blangkejeren - Laweaunan STA. 03 + 650, STA. 03 + 700, and STA. 03 + 750 which has a slope of each 63,4°(1H: 2V) concluded that the slope is not safe, so it needs a change of slope. After the change of slope on the slopes of the results showed that the slope of 30°-24°, the slope of qualified safety with a safety factor (STA. 03 + 650), from 1.299 to 1.468 (STA. 03 + 700) from 1.346 to 1.515 (STA. 03 + 750). Based on the results of the slope stability analysis obtained slope collapse semicircular arc (rotational sliding). The slope stability are qualified security that permitted 1 as recommended by Abramson (1996)
