Abstarct: The need for deep excavations in urban areas to construct buildings is essential and inevitable. Removal of loose surface soil and access to dense soil in lower levels, especially in deep excavations, significantly impact the soil stress distribution; Therefore, with the construction of earth retaining structures, non-safe movements of soil can be prevented. In urban environments, due to the low availability and small dimensions of lands, the use of a pile-anchor-wall method is a reasonable and suitable method, which generally had been modeled in two-dimensional in most cases. Meanwhile, with the development of computers, three-dimensional modeling of these structures is available. This study investigates the 3D modeling of the “Pazh” project with an approximate depth of 20 meters located in Mashhad city. The results show that reducing the length of anchors up to 2 meters can lead to the optimization of the structure economically. Also, a 2-degree reduction in anchor angle reduces stress and displacement. It has been observed that applying nonlinear dynamic loads such as earthquakes will increase the stresses on the excavation wall and anchors, increasing the probability of excavation damages. With increasing PGA and duration of an earthquake, maximum displacement and maximum pressure are raised on the wall and piles.
