Abstract

The construction of the Grand Dharmahusada Lagoon Apartment on Dharmahusada Mas, Mulyorejo, had a detrimental effect on the homes of local residents. Damage that occurs in general is cracks on the walls of the house ranging. Reinforcement using Diaphragm Wall and Secant Pile are designed for the Grand Dharmahusada Lagoon Surabaya project. Diaphragm wall and secant pile is a type of retaining wall that has the same advantages, the construction not noisy in workmanship, thickness and depth that can be adjusted as needed. The purpose of this thesis is to know and compare effectiveness of each plan. The results obtained in the calculation are material dimensions, wall depth, and maximum deformation. The Diaphragm wall has a thickness of 2.7 meters and a depth of 31 meters with a maximum deformation of 4.98 cm. In secant pile, the diameter of the pile is 1.2 meters with a depth of 31 meters and a maximum deformation of 4.93 cm. Based on the results of the planning comparison 2 of this method which includes maximum deformation, depth of excavation, wall thickness and estimated cost, planning was chosen using secant pile as a retaining wall.


ABSTRAK


Pembangunan Apartemen Grand Dharmahusada Lagoon di Jalan Dharmahusada Mas, Mulyorejo, membawa dampak buruk bagi rumah warga sekitar. Kerusakan yang terjadi pada umumnya adalah retak pada tembok rumah. Perencanaan perkuatan pada proyek Grand Dharmahusada Lagoon Surabaya menggunakan Diaphragm wall dan secant pile. Diaphragm wall dan secant pile merupakan jenis dinding penahan tanah memiliki keunggulan yang sama yaitu tidak bising dalam pengerjaan, ketebalan dan kedalaman yang dapat diatur sesuai kebutuhan. Tujuan perbandingan perencanaan dalam skripsi ini untuk mengetahui dan membandingkan keefektifan dari masing – masing perencanaan.. Hasil yang didapatkan pada perhitungan adalah dimensi material, kedalaman dinding, dan deformasi maksimum. Pada Diaphragm wall didapatkan ketebalan 2,7 meter dan kedalaman 31 meter dengan deformasi maksimum 4,98 cm. Pada secant pile didapatkan diameter pile sebesar 1,2 meter dengan kedalaman 31 meter dan deformasi maksimum 4,93 cm. Berdasarkan hasil perbandingan perencanaan 2 metode ini yang meliputi deformasi maksimum, kedalaman galian, ketebalan dinding dan estimasi biaya, dipilih perencanaan dengan menggunakan secant pile sebagai dinding penahan tanah.
