Abstract
Keberadaan tanah lunak merupakan salah satu tantangan dalam pembangunan infrastruktur di Indonesia. Pada kasus pembangunan gedung ITB Innovation Park, keberadaan tanah lunak mendominasi hingga kedalaman 21 meter. Kondisi tersebut menyebabkan daya dukung tanah menjadi rendah dan mengakibatkan potensi terjadinya penurunan pada bangunan jika tidak diatasi. Metode perbaikan yang dapat digunakan adalah dengan menggunakan timbunan pra-pembebanan dikombinasikan dengan Prefabricated Vertical Drain (PVD) dan Prefabricated Horizontal Drain (PHD). Metode ini bekerja dengan cara memberikan beban kepada tanah sehingga terjadi proses konsolidasi, tekanan ekses air pori pada tanah meningkat, dan laju disipasi air pori dipercepat melalui pita PVD dan PHD. Dalam penelitian ini, akan menggunakan software Midas GTS NX dalam kondisi 2D axisymmetric dan 2D plane strain dengan model konstitutif Mohr-Coulomb, Hardening Soil, dan Soft Soil Creep. Hasil pemodelannya akan dibandingkan dengan dua instrumentasi lapangan yaitu piezometer dan settlement plate. Nantinya, akan diketahui model konstitutif yang paling mendekati kondisi aktual di lapangan. Penelitian ini akan menggunakan metode deskriptif kuantitatif serta akan dilakukan analisis regresi dan R2 untuk pengambilan keputusan. Hasil pemodelan menunjukkan model konstitutif Soft Soil Creep dan Hardening Soil sebagai model yang paling cocok digunakan karena menghasilkan pembacaan tekanan air pori dan penurunan yang mirip dengan kondisi aktual, serta derajat konsolidasi yang paling konservatif. The existence of soft soil is one of the challenges in infrastructure development in Indonesia. In the case of the construction of the ITB Innovation Park building, the presence of soft soil dominates with a thickness of up to 21 meters. These conditions cause the bearing capacity of the soil to be low and result in the potential for settlement in the building if not fixed. The improvement method that can be used is fill preloading combined with Prefabricated Vertical Drain (PVD) and Prefabricated Horizontal Drain (PHD). This method works by giving a load to the soil so that the consolidation process occurs, the excess pore water pressure of the soil increases, and the pore water dissipation rate is accelerated through PVD and PHD bands. This study will use Midas GTS NX software in 2D axisymmetric and 2D plane strain conditions with Mohr-Coulomb constitutive models, Hardening Soil, and Soft Soil Creep. The modeling results will be compared with two field instrumentation, piezometer and settlement plate. Later, it will be known which constitutive model most closely approximates the actual conditions in the field. This study uses quantitative descriptive methods also regression analysis and R2 for decision making. Modeling results showed Soft Soil Creep and Hardening constitutive models as the most suitable models to use because they produce pore water pressure readings and decreases similar to actual conditions, as well as the most conservative degree of consolidation.
