The foundation is a structure under the building that serves as a distributor of the load on it to the supporting ground layer. The pile capacity is obtained from the soil investigation results which is a sondir test. Sondir test is a technique of soil layer estimator to determine the type of foundation that will be used such as pile foundation. Hydraulic Jacking System is a equipment to pressure the pile. Pile Driving Analyzer Test is a system used for test the pile dynamically after erection. The purpose of this research is to know the method of bearing capacity of pile foundation calculation based on sondir data which approach Hydraulic Jacking System capacity and Pile Driving Analyzer Test capacity. This research method is quantitative. Data were collected using survey techniques. The survey technique is used to obtain generat data from the field. The data is processed using Schmertmann’s method, Philipponant’s method, and Andina’s method, and the results is compared with the Hydraulic Jacking System capacity and Pile Driving Analyzer Test capacity.

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 . Dalam merencanakan pondasi untuk suatu struktur dapat menggunakan beberapa macam tipe pondasi. Pemilihan pondasi berdasarkan fungsi bangunan atas yang akan dipikul oleh pondasi tersebut, berdasarkan beban dan beratnya bangunan atas kedalaman tanah dimana bangunan tersebut didirikan. Pembangunan gedung C berlantai 7 Universitas Kadiri memerlukan pondasi yang kuat. Pondasi tiang pancang dipilih karena pekerjaan relatif cepat, mudah dan hasil sondir tanah keras pada 5,6 m. Pada perhitungan ini digunakan tiga metode yaitu metode Trofimankove dan metode mayerhoff serta Metode cara Umum. Perencanaan pondasi tiang pancang memiliki beban rencana sebesar Qu 231 Ton. Dari perhitungan ketiga metode didapat hasil yang lebih efisien yaitu pada perhitungan dengaan metode mayerhoff yaitu sebesar 82,21. Jumlah tiang tunggal yang mendekati pada satu pile cap adalah 4 tiang, sehingga diperoleh dari rumus perhitungan Pall tiang kelompok 232,82 Ton. Dengan demikian dapat disimpulkan Pmaks < Pall 231 Ton < 232,82 Ton, yang artinya memenuhi syarat.

One of the most important factors in the structure of the pile foundation in the construction of the bridge is the carrying capacity of the soil so as not to collapse. Construction of a bridge in the village of Klitik in Jombang Regency to be built due to heavy traffic volume. The foundation plan to be used is a pile foundation with a diameter of 50 cm, the problem is what is the value of carrying capacity of soil and material.

Generally, pile foundation is typically chosen to support heavy structures. However, the developments of expressions to determine the pile capacity is usually based on fully saturated and completely dry conditions. In fact, almost 40 percent of natural soils on the earth surface are in an unsaturated state. Thus, in this paper, an expression for pile capacity in homogeneous unsaturated sand layer is developed. The simulations using developed expression are performed and discussed. Typical results show that the pile capacity and the factor of safety are affected by matric suction. However, the influence of matric suction may be ignored for a long pile.

Major Factors

Pile Dynamic Formulas are the oldest and frequently used method to determine bearing capacity of piles. The more recent method is based on the Wave Equation analysis and different formulations such as Case Mathod, TNO, CAPWAP and TEPWAP which were developed for pre-driving analysis and post-driving measurements applications. The major factors for the common use of the dynamic formulas have been due to their simplicity, cost effectiveness and applicability in various piling situations. However, in some literature the energy approach have been given an unfair reputation as being unreliable and less accurate than the more analytical or dynamic testing methods. One of the issues due to the poor performance of the dynamic formulas is that, historically, the hammer energy and the energy trasferred to pile had to be assumed. Nevertheless, with the advent of computers, new technologies are emerging with the advancement in construction industry. This has produced gradual improvements that have resulted in the dynamic method to be used on many projects with greater reliability. In this paper, a review of the different testing methods as well as pros and cons of the pile driving formulas are discussed. Also, an approach to improving the widely used Hiley dynamic equation is presented. This approach enables evaluation of the pile capacity to be made more accurately.

Superior Approach

Capacity measures a system’s ability to survive stress. For example, structures are engineered in part to have the capacity to survive the worst wind loads expected over the life of the structure. Likewise wind electric power systems should have the capacity to reliably survive the worst combination of high load and low wind. A superior approach for quantifying wind’s contribution to system capacity is well known. It is to view wind as a negative load and use the Effective Load Carrying Capacity (ELCC) methodology for a given year. A frequent mistake is to average these annual ELCC estimates. A main contribution of this paper is to explain why the system design criteria should take the worst of the annual ELCC estimates over a number of years and not an average of annual ELCC estimates. Based on extreme events, wind generation contributes little to system capacity (<6.6% of wind nameplate). The empirical evidence shows that wind generation is an energy source, not a capacity resource.

This paper reports the research carried out using Structure from Motion survey techniques, which were developed on the basis of previous surveys and their subsequent representation through two-dimensional (2D) and three-dimensional (3D) drawings of the tomb, comparing them with drawings and watercolors by several painters of the past. This survey technique enables the reconstruction of three-dimensional models through photographs. The aim of this work is to define a procedural process which allows accurate and reliable three-dimensional reconstructions to be performed for the acquisition of knowledge and the dissemination of cultural heritage, taking advantage of representation and visualization techniques that have been developed in the last decade and that are based on historical references. The variety of digital products which can be produced (video games, 3D models, prints, websites, and augmented reality applications) allows a different approach to the representation to be taken, thereby re-evaluating limits, aims, and expressive potential. The virtual representative systems, enriched with cultural content, scientific information, and data, enhance the participation and awareness of knowledge of the final users of the products and are able to increase the interaction between the user and the information.
