Several studies have already been published in order to better understand the behaviour of interfaces. Different experimental methods, including direct shear tests, simple shear test, and tortional ring test, and also various constitutive models were presented to modelize the behaviour of the interface. These studies revealed that the main factors that affect the behaviour of the interface include the roughness of the interface, the soil mineralogy, the soil density, and the normal stress applied. This work was therefore directed primarily to better understand the overall behaviour of the interface and the influence of these factors in a monotonic and cyclical solicitation. Through the simulation of a direct shear test at constant normal stress (CNL) in FLAC 5.0, several typical behaviours, including degradation of shearing resistance and contractancydilatancy, have been observed and modelled. At first, the law of Mohr-Coulomb and its correspondent failure criterion have been implemented. Then several models have been proposed to model more precisely the behaviour. Finally, two cyclicals laws, the law of Ramberg-Osgood law and Byrne, originally developed for the soil, have been implemented in this model. This study has verified the consistency of the results and has determined whether the injection of such laws is sufficient to modelize the behaviour of the interface under cyclic loading.

Di perancis Kontrol Teknik atau Kontrol Kualitas adalah sebuah aktivitas yang didasarkan pada hukum Spinetta yang dikeluarkan pada tanggal 4 januari 1978, atas permintaan dan sebagai perwakilan dari klien. Sejak saat itu kontrol teknik menjadi wajib untuk projek projek khusus, seperti konstruksi bangunan untuk publik; bangunan dengan tinggi lantai terakhir adalah lebih dari 28 m dari lantai dasar bangunan dan bangunan dengan tujuan selain industri yang memilki struktur kantilever lebih dari 20 m, balok berbentuk arc lebih dari 40 , bagian dari struktur yang berada dibawah tanah sedalam mebih dari 15 m , pondasi dengan kedalaman lebih dari 30 m, dinding penahan gaya horizontal yang besebelahan lebih dari 5 m. Misi utama kontrol teknik ini adalah untuk membantu pencegahan berbagai resiko teknik dalam penyelesaian suatu projek dan selama masa servicenya. Tiga misi utama dari control teknik adalah: Misi kekuatan dan stabilitas dari bangunan, misi keamanan dan keselamatan selama periode konstruksi dan penggunanan serta misi kemudahaan penggunanan fasilitas gedung untuk orang cacat. Pada kesempatan ini saya berhasil mengikuti berbagai projek seperti konstruksi perumahan, kolam renang, kompleks olahraga dan lain-lain. Disini saya menganalisa berbagai dokumen dan gambar teknik berbagai bidang berbeda (konstruksi beton, metallik, pondasi spesial, atap, pengevakuasian asap dll) yang akan kemudian digunakan dalam sebuah projek. Saya juga mendapat kesempatan untuk membuat dan berpartisipasi dalam pembuatan berbagai dokumen seperti: daftar hal ? hal penting yang harus diperhatikan atau diperbaiki dalam sebuah dokumen dan gambar teknik dan exekusi, laporan kontrol teknik dan laporan inisial. ......In France the Technical Control is a reviewed exercise within the framework of the Act Spinetta on January the 4th, 1978, at the request and on behalf of a client. It has since become mandatory for certain operations such as construction of facilities to the public; buildings whose floor bottom of the last level is more than 28 m above the ground and the buildings other than industrial use with a cantilever of more than 20 m; arc beams which is greater than 40 m; parts of a construction buried more than 15 metres deep; foundation of more than 30 m; or jacks neighbours over 5 m. The Technical Control?s main mission is to contribute to the prevention of various technical uncertainties in achieving the works. Its three main missions are: the mission of strength, the mission of security for the people before and after construction and the mission of handicapped accessibility. In this opportunity I was able to attend several operations such as the construction of houses, pools, sports complexes, and so on. I had the opportunity to analyze various technical papers and execution plans for different fields (Outside Carpentry, Roofs, Smoke evacuation, Concrete Construction, Special Foundation and Metallic construction). I also had the opportunity to write and collaborate in the creation of many documents such as list of notices for an execution document and plan, the report of a technical control, an initial report.
