Soil Investigation Analysis Bearing Capacity of Caisson Foundation Makassar City Bblk Service Building

Soil investigation is an effort to obtain underground information for planning civil building foundations. The existence of a soil investigation can determine the bearing capacity of the foundation. One type of foundation that is planned is a caisson foundation. Soil investigation includes, among others, soil drilling, soil sampling, field testing and laboratory testing. A Referring to the technical data, the caisson foundation plan scheme used has a diameter of 60-1000cm, the selection of the most suitable diameter is adjusted to the load plan of the superstructure while the foundation depth is recommended to pass through a bedrock layer of 20-30cm. Technically, the soil layer is sufficient to withstand vertical loads, this is indicated by the value of Qc>150kg/cm2 and NSPT>60, but the location of the building is on sloping land with the distribution of bedrock layers that have a slope following the profile of the soil surface, so the potential for uplift is ) can occur due to lateral forces, this is also supported by the uneven embankment material from the original soil surface profile so that the load acting is uneven on the embankment layer.
