Abstract


Abstract. The practice of mining general bearing capacity of the soil against the foundation can be associated with some infrastructure that will be used in mining activities, like the Smelter, workshop dst. Knowledge of bearing capacity is important, important considering that all activities will be related to the foundation of the land on which it is located. The research methodology used in this research such as literature study, data collection (field observation and laboratory testing), and Analysis used is to correlate all data that has been processed using manual calculations based on Mayerhoff's theoretical approach and converse labate. Research Soil bearing capacity aims (1)to determine the soil characteristics that will be used to calculate the bearing capacity of the pile foundation, (2) obtain soil bearing capacity (qu) from SPT results and (3) soil shear strength parameters, (4) Obtain SF value from single pole capacity, and obtain ultimate group pile capacity (qun). From field observations, drilling activities and laboratory test results it is known that the research area is dominated by clay material CH and MH. From the results of SF calculations on the Bearing capacity of the lab test results obtained a value of 1.7234 and from the Bearing capacity of the SPT obtained an SF value of 1.6681, the following are the results of all observation points on the 6m depth foundation. From the calculation results obtained the value of the pile foundation permit Bearing capacity of 2205 kN.

Keywords: Mayerhoff, Bearing Capacity, Pile Fondation, Safety Factor.

Abstrak. Dalam dunia pertambangan daya dukung tanah terhadap pondasi secara umum dapat dikaitkan dengan beberapa infrastruktur yang akan digunakan dalam kegiatan pertambangan, seperti pada Smelter, workshop dst. Pengetahuan  mengenai daya dukung merupakan hal yang penting mengingat segala kegiatan akan berhubungan dengan tumpuan tanah yang tempat berdirinya. Metodologi penelitian yang digunakan meliputi beberapa tahapan seperti studi literatur, pengambilan sata (observasi lapangan dan pengujian laboratorium), dan Anaslisis yang digunakan adalah mengkorelasikan semua data yang telah di olah dengan menggunakan perhitungan manual berdasarkan pendekatan teori Mayerhoff dan converse labate. Penelitian Daya dukung tanah bertujuan (1) mengetahui karakteristik tanah yang akan digunakan untuk menghitung daya dukung pondasi tiang, (2) memperoleh daya dukung tanah (qu) dari hasil SPT dan (3) parameter kuat geser tanah, (4) memperoleh nilai SF dari kapasitas  tiang tunggal, serta memperoleh kapasitas ijin kelompok tiang (qun). Dari kegiatan observasi lapangan, kegiatan pengeboran dan hasil uji laboratorium diketahui bahwa area penelitian di dominasi oleh material tanah lempung berlanau.CH dan MH. Dari hasil perhitungan SF pada daya dukung dari hasil Uji lab didapat nilai sebesar 1.7234 dan dari daya dukung SPT didapat nilai SF sebesar  1.6681, berikut merupakan hasil dari seluruh titik pengamatan pada pondasi kedalaman 6m.  Dari hasil perhitungan didapat nilai daya dukung ijin pondasi tiang kelompok sebesar 2205 kN.

Kata Kunci: Mayerhoff, Daya dukung, pondasi tiang, Faktor Keamanan.
