Abstract

Expansive soils contain the mineral montmorillonite, which is highly susceptible to changes in moisture content and can easily expand or shrink and subsequently damage the foundation or building above it. Foundation design is important in the construction of a structure and must be properly considered to strengthen the structure. In this study, we want to know the value of changes in the bearing capacity of the pile foundation during soil expansion and shrinkage. And also examine the value of bearing capacity and foundation settlement when there is a change in groundwater level. Because the clay soil shrinks and expands, the negative skin friction and heave analysis of the piles is also carried out. The results of the analysis were obtained using 2D finite element applications. Based on the results of the analysis of the bearing capacity value and soil settlement, the fluctuation of the groundwater table elevation is one of the influential factors, at low elevations the bearing capacity value is greater and the soil settlement is smaller, then at high elevations the opposite will occur. Meanwhile, when the soil is drained, it will produce a greater bearing capacity value than when it is undrained. Abstrak Tanah ekspansif mengandung mineral montmorilonit, yaitu mineral yang sangat rentan oleh perubahan kadar air sehingga mudah mengalami muai atau susut lalu selanjutnya merusak fondasi atau bangunan di atasnya. Perancangan fondasi adalah hal yang penting dalam pembuatan struktur dan harus dipertimbangkan secara tepat untuk memperkuat struktur. Dalam penelitian ini, kami ingin mengetahui nilai perubahan daya dukung fondasi tiang saat terjadi muai susut tanah. Dan juga meneliti nilai daya dukung dan penurunan fondasi ketika terjadi perubahan muka air tanah. Karena tanah lempung mengalami susut dan kembang, maka dilakukan juga analisis negative skin friction dan heave pada tiang pancang Hasil analisis didapatkan menggunakan aplikasi elemen hingga 2D. Berdasarkan hasil analisis nilai daya dukung dan penurunan tanah bahwa fluktuasi elevasi muka air tanah merupakan salah satu faktor yang berpengaruh, pada elevasi rendah nilai daya dukung semakin besar dan penurunan tanah semakin kecil maka pada elevasi tinggi akan terjadi kebalikannya. Sedangkan pada saat tanah dalam kondisi drained akan menghasilkan nilai daya dukung yang lebih besar daripada saat kondisi undrained.

Abstract

Expansive soil is a soil that easily expands and shrinks when there is a change in moisture content. The nature and characteristics of expansive soil have a dangerous impact on building structures such as foundation failure and cracking. This research will approach the correlation of soil parameters that have not been tested in the laboratory to obtain values that are close to field tests. In addition, it classifies the soil type into a certain level of expansiveness based on the approach taken. In this study, it was found that the expansive soils in each project have a development potential of "high-very high" based on the activity value with the percentage of clay grain fraction. Furthermore, based on the plasticity index relationship, the soils in all three projects have a development potential at the "very high" level. In addition, it was identified that the soils of the three projects have montmorrillonite mineral which validates that the soil type belongs to expansive soil type. The relationship of the parameters LL, PL and PI to swelling pressure (Psw) resulted in linear regression equations Psw = -0.0086 LL + 0.8268, Psw = -0.0139 PL + 0.5369, and Psw = -0.004 PI + 0.1619. Abstrak Tanah ekspansif merupakan tanah yang mudah mengalami kembang susut ketika terjadi perubahan kadar air. Sifat dan karakteristik tanah ekspansif ini memiliki dampak berbahaya bagi struktur bangunan seperti kegagalan fondasi dan keretakan. Pada penelitian ini akan dilakukan pendekatan terhadap korelasi parameter tanah yang belum diuji laboratorium untuk memperoleh nilai yang mendekati uji di lapangan. Selain itu, mengklasifikasikan jenis tanah termasuk ke dalam tingkat keekspansifan tertentu berdasarkan pendekatan yang dilakukan. Pada penelitian ini, diperoleh bahwa tanah ekspansif pada setiap proyek memiliki potensi pengembangan dari “high–very high” berdasarkan nilai aktivitas dengan persentase fraksi butiran lempun. Kemudian, berdasarkan hubungan indeks plastisitas tanah pada ketiga proyek memiliki potensi pengembangan pada tingkat “sangat tinggi”. Selain itu, diidentifikasi bahwa tanah dari ketiga proyek memiliki mineral montmorrilonite yang memvalidasi bahwa jenis tanah termasuk ke dalam jenis tanah ekspansif. Hubungan parameter-parameter LL, PL dan PI terhadap swelling pressure (Psw) menghasilkan persamaan regresi linier Psw = -0,0086 LL + 0,8268, Psw = -0,0139 PL + 0,5369, dan Psw = -0,004 PI + 0,1619.
