PERENCANAAN PONDASI TIANG PANCANG TIPE (SPUN PILE) PADA GEDUNG PENGADILAN AGAMA PENAJAM PASER UTARA KALIMANTAN TIMUR

In terms of planning the foundation of the North Penajam Paser Religious Court building, East Kalimantan, it is necessary to carry out a soil research survey (Soil investigation). Deep foundations are used when the hard soil layer is at a very deep depth. It is also used to support buildings that resist upward lifting forces, especially in high-rise buildings that are affected by overturning forces due to wind loads. The depth of hard soil reaches 4 - 5 m from the ground surface or D/B is around 4 and is usually used for large buildings, bridges and offshore structures.
In designing a pile foundation, data is absolutely necessary about the subgrade and the load that the structure will support. These two things are very necessary to determine the carrying capacity of a single pile or group pile and analysis to anticipate negative skin friction, because negative skin friction can result in additional loads. For this reason, it is necessary to carry out sondir and boring tests to determine soil data. The bearing capacity of the pile is obtained from the end bearing capacity which is obtained from the pressure of the end of the pile and the shear or blanket power (friction bearing capacity) which is obtained from the friction bearing capacity or adhesion. between the pole and the soil around it.
