General Method

The foundation is a part of the structure that functions as a support for the building and distributes the burden on it (upper fabric) or the soil layer with a stable enough carrying capacity. In planning the foundation for a structure can use several types. The selection of the foundation to be used based on the weight of the building. The construction of the C story building seven-story University requires a strong foundation. The pile foundation was chosen because it was relatively fast, easy, and yielded hard soil at 5.6 m. In this calculation, three methods as a Trofimankove method and the Meyerhoff method and the General Method Method. Pile foundation planning has a planned load of Qu 231 Ton. The calculation of the three ways obtained more efficient results, namely the count with a Meyerhoff method equal to 82.21. The number of single piles that are close to one pile cap is four poles, so the calculation formula of the Pall piles group is 232.82 tons. Thus it can be concluded that Pmax <Pall 231 Ton <232.82 Ton, which means that it meets the requirements.Pondasi adalah bagian struktur yang berfungsi sebagai penopang bangunan dan menyalurkan beban diatasnya (upper structure) atau lapisan tanah yang memiliki daya dukung yang cukup kuat .

Abstract The use helix pile foundations in supporting structures on peat soil has became a challenge for road infrastructure. The helix pile foundation is an alternative for substituting the pile foundation if hard soil is located too far from the surface. Therefore, in this study we examine the bearing capacity of the helix pile foundation on peat soil, including analyzing the effect of the number of helix plates on the bearing capacity of the peat soil. The type of foundation used is a helix pile foundation with a single blade, double blades and triple blades. From the results of the research the bearing capacity of helix double is 35% greater than the bearing capacity of a single helix, the value of triple helix bearing capacity is 25% greater than the double helix and 70% of the single helix. The more number of helix plates used, the greater the bearing capacity of the piles given.

Load Carrying

Pile foundation is one of the effective forms of deep foundation. This is to be used where the load has to be transferred to deeper layers of soil and it can with stand uplift forces in foundations in expansive soil and also in case of floating foundations. The finite element method is one of the most versatile and comprehensive numerical technique which can be used for analysis of structures or solids of complex shapes and complicated boundary conditions. There are different variables which influence the load carrying capacity of pile foundation. But only some of those have significant influence on load carrying capacity. Here those variables are considered and the variation of load carrying capacity with the change in value of those variables is observed. Those variables are pile length and pile diameter, analysis of pile foundation was carried out to determine the ultimate load carrying capacity of pile for different lengths and diameters in cohesive soil, the corresponding settlement was also determined.

Soil bearing capacity is the ability of the soil to support the foundation load acting on it. To produce an accurate bearing capacity, it is necessary to know the properties and characteristics of the soil. For this reason, a comparison of the carrying capacity of the soil is carried out based on the calculation of CPT / Sondir and SPT to be able to plan a safe and economical pile foundation. The purpose of this study was to determine the amount of soil bearing capacity of the deep foundation in the environment around the Ataqwa Mosque, Baringin Village, Palangkaraya City based on field tests, and based on laboratory tests, and to determine the value of the comparison between the Mayerhof Method and the Schmertmann-Nottingham Method. Based on the Sondir value, it is continued with the calculation of the carrying capacity of the soil, then the calculation results are analyzed and concluded. From the calculation of the value of the carrying capacity of the foundation pile implementation of point 1 (one), the highest value of 400 mm diameter piles in the Meyerhoff method is 75,319 kg, while the lowest bearing capacity value is also at 400 mm piles of 10,676 kg.

Engineering geological aspect and bearing capacity of pile foundation are significant for safety of upper structure, especially for substantial constructions such as a docking ship. Moreover, it provides effectiveness and cost efficiency when applies in rural areas of Indonesia. This is due to lack of docking ship appropriately built at rural areas particularly in eastern areas of Indonesia. Karim island of Papua even though is a small island yet is very strategic as Pertamina place its transitory function on that island connecting its oil supply route to Sorong. Appropriate docking ship construction is required to aim the effective and efficient port management. Choosing the most suitable structure for a docking is also the key. Graving dock structure has been chosen by Pertamina as the most appropriate type of structure for the docking ship in Karim Island. The structure of graving dock planned to be built in Karim island Papua, is projected to be able to serve the maximum 7500 DWT ship capacity, with approximately dimension is 125 x 25 x 8 meters. Therefore, to support the plan, type and design of the best foundation is the key. There are two methods could be done in determining the type and bearing capacity foundation. Field and laboratory test applied ASTM, field observation result by applying Meyerhoff theory and laboratorial analysis derived from Tarzaghi theory. Those observation and analysis has confirmed that the soil layer at the graving dock design consists of three layers, those are; cover layer, silt-clay layer and clay rock unit. Therefore, the most suitable foundation to be constructed in that area is a pile massive foundation, with depth of pile foundation approximately -20 m below the land surface, and the ultimate point load pile massive for 30x30 cm – 75x75 cm dimension approximately 79.76 – 406.25 ton, and frictional resistance value approximately 24.59 – 61.48 ton.
