Preliminary Study

Airtanah merupakan salah satu faktor penting yang berkontribusi terhadap ketidakstabilan lereng, air akan mengisi pori tanah sehingga tekanan air pori meningkat. Pada tahun 2009 di Pit E, PT. BC khususnya low wall pernah terjadi longsor, tujuan penelitian ini untuk mengetahui besar penurunan muka airtanah (drawdown) serta melakukan simulasi dalam waktu 8 tahun kedepan setelah upaya dewatering pada tahun 2016 dengan menggunakan sistem drain hole yang dipasang secara inclined. Model konseptual daerah penelitian dibangun dengan data pengamatan muka airtanah mula-mula, curah hujan, topografi dan properti hidrogeologi yang ditentukan berdasarkan asumsi teoriritis. Simulasi numerik menggunakan metode beda hingga dilakukan dalam dua skenario yaitu pada tiga IDH aktif dan penambahan tiga IDH di luar model pada akuifer terkekang dengan variasi kedalaman 50 m dan 80 m. Drawdown hasil simulasi kemudian dikalibrasi dengan perhitungan metode Theis. Hasil studi menunjukan nilai drawdown dari perhitungan Theis lebih kecil dari hasil simulasi numerik. Outflow pada pemodelan juga menghasilkan nilai yang lebih besar dari pengamatan di lapangan. Parameter adjustment berupa nilai konduktivitas hidraulik kemudian dilakukan untuk mengetahui pengaruhnya terhadap besar drawdown. Hasilnya menunjukan bahwa nilai konduktivitas hidraulik memiliki pengaruh yang signifikan terhadap perubahan besar drawdown.

Design Result

According to a series of characteristics produced from the side cutting in the rotary steering drilling system, PDC bit is improved from the profile shape, cutting structure, and gauge structure. Also, suggestions are proposed according to the drilling parameters of operation. The study result shows that the requirements of the rotary steering drilling system can be fulfilled by PDC bit design result and drilling parameter adjustment.

Purpose: Prediction of geomechanical state of soft-soil foundation of buildings before and after compaction, reinforcement or stabilization. Calculation of parameters of pressure injec-tion while stabilizing the soft man-made soil foundation, development of recommendations for parameter adjustment of pressure injection.Methods: Numerical methods and computer mod-eling of the soil foundation using the finite element method for studying its geomechanical state of a mining building with regard to heterogeneities of the local geological structure and changes in the physical and mechanical properties of soils.Research findings: The obtained results are based on engineering and geological surveys of the soil foundation of the mining building composed of man-made bulk soils. The stress-strain state of the soil foundation is simulated. As a result of injection compaction the geomechanical state of the soil mass chang-es.Practical implications: Recommendations are given for the parameter adjustment of the injection method. It is shown that the pressure injection method is undoubtedly effective for the soil stabilization for buildings.
