Abstract
Sebagai sentra ekonomi dan bisnis terdepan di Pulau Sumatera menciptakan peluang besar berkembangnya sektor bisnis properti di Kota Medan. Hotel Ibis Merah merupakan sebuah hotel yang akan dibangun di Jalan Gajah Mada No.21, Medan. Hotel Ibis Merah ini direncanakan memiliki 15 lantai dengan 3 lantai basement sebagai lahan parkir, GWT, dan STP. Total kedalaman galian Hotel Ibis Merah Medan dibagi menjadi 2 zona, yaitu zona 1 kedalaman galian 9,5 m dengan secant pile panjang 22 meter yang berada pada sisi Jalan Gajah Mada dan zona 2 kedalaman galian 5,8 m dengan secant pile panjang 10 meter yang berada pada sisi bangunan Pizza Hut.
Metode pelaksanaan dinding penahan tanah menggunakan teknik bored pile agar menghindari adanya getaran yang berlebih saat pelaksanaan konstruksi sehingga meminimalisir dampak kerusakan pada bangunan maupun fasilitas umum disekitar proyek. Konstruksi dinding penahan tanah secant pile juga didukung oleh pemasangan sistem penunjang berupa strutting baja pada area zona 1 galian 9,5 m.
Berdasarkan hasil pemodelan, untuk secant pile sisi Jalan Gajah Mada dengan perkuatan satu layer strut didapatkan total horizontal displacement terbesar adalah 0,07677 m sedangkan untuk sisi bangunan Pizza Hut sebesar 0,2603 m. Sehingga dilakukan redesain terhadap kedua sisi secant pile dari segi dimensi dan sistem perkuatan agar dapat memenuhi kriteria SNI. Sesuai hasil perhitungan ulang, sisi Jalan Gajah Mada menggunakan secant pile Ø800 mm panjang 20 meter dengan perkuatan 3 layer strut menghasilkan total horizontal displacement terbesar adalah 0,04754 m sedangkan sisi bangunan Pizza Hut menggunakan secant pile Ø800 mm panjang 16 meter dengan perkuatan 2 layer ground anchor menghasilkan total horizontal displacement terbesar adalah 0,0289 m.
============================================================
As the leading economic and business center in the island of Sumatra creates a great opportunity to grow the property business sector in Medan. Hotel Ibis Merah is a hotel that will be built on Jalan Gajah Mada No. 21, Medan. Hotel Ibis Merah is planned to have 15 floors with 3 basement floors as a parking lot, GWT, and STP. Total depth of excavation Hotel Ibis Merah Medan is divided into 2 zones, zone 1 of 9.5 m depth excavation with secant pile of 22 meters length that is on the side of Gajah Mada Street and Zone 2 of the 5.8 m depth excavation with a secant pile of 10 meters length that is on the side of the Pizza Hut building.
The implementing method of soil retaining wall using bored pile technique to avoid excessive vibration during construction implementation so as to minimize the impact of damage to buildings and public facilities around the project. retaining wall construction of secant pile is also supported by installation of supporting system in the form of steel strutting on zone 1 of 9.5 m depth excavation.
Based on the results of modeling, for the secant pile side of Gajah Mada Street with the retrofitting of one layer strut obtained the largest of total horizontal displacement is 0,07677 m while for the side of the building Pizza Hut is 0,2603 m. So it is redesigned against both sides of the secant pile in terms of dimensions and the system of retrofitting to meet the criteria of SNI. As the result of the recalculation, Gajah Mada Street used a secant pile Ø800 mm length of 20 meters with the retrofitting of 3 layer strut produce the largest of total horizontal displacement is 0,04754 m while the side of the building Pizza Hut using a secant pile Ø800 mm in length 16 meters with the retrofitting 2 layer ground anchor produce the largest horizontal displacement is 0,0289 m.
