Soil Investigation Analysis Using the Sondir Testing Method in The Jalan Pura Demak Area, Denpasar

Povzetek

The structure is calculated not only based on its own load bearing strength but must also take into account the soil bearing capacity. The soil bearing capacity is the maximum load per unit area where the land can still support the load without collapsing, taking into account safety factors (1). One way to find out the carrying capacity of land permits is by direct sondir testing in the field. In this research, sondir testing was carried out in the Jalan Pura Demak area, Denpasar. This location was chosen because of the rapid development in the area. Soil testing was carried out at three adjacent points. From the results of the sondir test, it was found that hard soil conditions began to be detected by the tip of the sondir cone at a depth of 2.8 meters (point 1), a depth of 3 meters (point 2) and a depth of 3.2 meters (point 3). Soil bearing capacity is analyzed using the Meyerhoff formula (2). The analysis results show that if the structural load is light, the use of reinforced concrete footings has provisions starting at a foundation depth of 1.6 meters from the ground surface and a soil bearing capacity of or 102 KN/m2.Meanwhile, for relatively heavy structural loads, it is recommended to use pile foundations with a depth of more than 3 meters from the ground surface, with a soil bearing capacity of 613 KN/m2.
