The construction industry is one of the key industries of every country that has a great impact on the economy because a significant percentage of the country budget is annually allocated to the construction budget. With the arrival of the fourth industrial revolution, the scope of applying technologies in the field of construction has been expanded. The construction industry has experienced a tremendous transformation with the approach of digitization and the involvement of new technologies, and this evolution has a significant impact on meeting the needs and processes in the construction industry. Among the technologies that have provided a platform for the digitization of the construction industry is construction information modeling, a process in which the management and production of construction project information is carried out in a coherent and integrated manner, and it causes group cooperation, effective coordination of project elements and more detailed designs. The tunnel is one of the most widely used projects in the construction industry that is used for various purposes such as transportation, mineral extraction, directing the flow of underground and surface water, installation of facilities, etc. In this paper, analysis of the benefits of construction information modeling in tunnel projects according to the research conducted from 2010 to 2022 in a case study is presented following implementation of construction information modeling in the tunnel of Namaz Square metro station in Islamshahr located in Tehran Province.

A simple developed thin - layer element from the interface of the soil and structure is used in a finite element process to simulate different operating modes of soil - structure dynamic interaction. The constitutive behavior of the interface is defined by splitting it into its cutting and normalized components. Nowadays, using pieces of worn-out rubber is a suitable method to strengthen the soil and increase the soil loading capacity. It is also a way to recycle rubber waste materials. With the knowledge that more behavioral compatibility with the soil and concrete interface has a better damping effect in the quake-separator, in order to simulate the behavior of the interface, soil and rubber were used with different percentages of 10, 20, 30 and 40 percent which provided acceptable results in the modeling of the intersection of soil and concrete.
