Abstrak

Prediksi daya dukung tiang menjadi tantangan sejak lahirnya profesi geoteknik. Daya dukung tiang yang digunakan dalam penelitian ini menggunakan hasil uji investigasi in-situ secara langsung/tidak langsung dan pengujian dinamis dengan PDA. Tujuan penelitian adalah melakukan perhitungan (awal) analisis daya dukung ultimate per lokasi per kedalaman, melakukan model prediksi dengan metode empiris, melakukan perhitungan (model) analisis daya dukung ultimate per lokasi per kedalaman, selanjutnya melakukan pemilihan metode perhitungan analisis yang paling ideal berdasar batasan penelitian serta penentuan nilai koefisien tahanan ujung dan tahanan lekatan. Analisis dilakukan berdasar Metode Meyerhof, Metode Bazara dan Kurkur, Metode Briaud dan Tucker, Metode Luciano Decourt, dan Metode Shariatmadari. Analisis pada data awal dihasilkan nilai NSE yang tidak memuaskan. Model prediksi dilakukan dengan metode empiris, yaitu mengubah nilai tahanan ujung dan tahanan lekatan agar daya dukung ultimate untuk seluruh metode analisis dihasilkan nilai yang sama dengan v hasil PDA, kemudian dicari nilai reratanya dari hasil model prediksi itu. Berdasar nilai rerata tersebut, dilakukan perhitungan (model) analisis daya dukung ultimate untuk seluruh metode analisis. Perhitungan metode analisis berdasarkan Metode Briaud dan Tucker dengan nilai nb = 0,1265 dan nilai ns = 1,3005 dihasilkan nilai NSE = 0,8559 (kriteria sangat baik). Kata kunci: daya dukung ultimate, daya dukung hasil PDA, model prediksi, metode empiris, koefisien tahanan ujung dan koefisien tahanan lekatan. vi ABSTRACT PREDICTION MODEL OF ULTIMATE BEARING CAPACITY OF PILE BASED ON EMPIRICAL METHOD: STUDY CASES ON PATIMBAN PORT By: Hadi Triolaksana How to predict pile’s bearing capacity has been a challenge since the beginning of geotechnical engineering. Pile’s bearing capacity that is used in this research are taken from the results of direct/indirect in-situ investigation test and dynamic testing such as PDA Test. The objectives of the research are to perform initial analysis of the ultimate bearing capacity at certain location per depth, to perform predictive models with empirical methods, to perform calculation (model) then analyze the ultimate bearing capacity at certain location per depth, and choose the most ideal analytical calculation method based on research boundaries and determination of the end and frictional bearing coefficient. The analysis was carried out based on the Meyerhof Method, Bazara and Kurkur Method, Briaud and Tucker Method, Luciano Decourt Method, and the Shariatmadari Method. Analysis with initial data produced unsatisfactory NSE values. Prediction model is carried out by an empirical method, which change the end and frictional bearing vii so that the ultimate bearing capacity for all analysis methods has the same results with the PDA results, then the average of the predicted model can be determined. Based on the average values, a calculation (model) of ultimate bearing capacity for all of the analysis method can be performed. The result of the analysis method based on Briaud and Tucker method is nb = 0,1265 and ns = 1,3005 with the NSE Values = 0,8559 (very good categories). Key words: ultimate bearing capacity, ultimate bearing based on PDA, prediction model, empirical model, end bearing coefficient and frictional bearing coefficient.
