Abstract

Static Loading Test (SLT) merupakan salah satu metode pengujian daya dukung pondasi yang dapat dipercayai, namun menghabiskan biaya yang cukup besar dan waktu yang relatif lama. Hal ini membuat Pile Driving Analyzer (PDA) menjadi metode alternatif pengujian beban aksial pondasi tiang semakin banyak diminati. Penelitian ini bertujuan untuk mempelajari korelasi nilai daya dukung ultimate hasil PDA dengan SLT yang diinterpretasikan dengan metode Davisson (1972), Chin (1985), Mazurkiewicz (1972) dan Decourt (1999). Dari hasil perbandingan, diketahui bahwa nilai daya dukung ultimate hasil PDA memiliki rentang yang paling mendekati dengan hasil SLT yang diinterpretasikan dengan metode Chin. Selain itu, daya dukung ultimate hasil SLT yang diinterpretasikan dengan metode Chin dan Davisson paling mendekati nilai beban ultimate rencana.

Abstract

Lateral movement of soil due to the installation of a single pile using jack-in method was studied. The piles considered in this study were 15 piles of the diameter 800 mm. The lateral soil movement was predicted using Plaxis 2D, which incorporated cavity expansion theory as prescribed displacement. The results were compared to the recorded data from the field and those determined using several formulas. The comparison shows that the lateral movement of soil due to the installation of a single pile can be closely estimated using Plaxis 2D that employed a linear prescribed displacement of 0.42r at the pile head and zero at the pile tip. Lateral displacement of soil predicted using Plaxis 2D agrees well with data measured from the field both at the ground surface and along the depth of piles.
