NUMERICAL STUDY OF INVESTMENT BEHAVIOR CONTAINMENT WALLS (CASE STUDY STRUCTURAL GUARDIAN SYSTEMS PROJECT OF HABIB HOTEL OF MASHHAD)

Abstract

Safe and economic design of containment walls under lateral loads (soil thrust and earthquake) is
of particular importance in urban areas, especially in recent years with the increase in
construction, excavation operations in some structures such as towers are necessary, despite
stabilizing adjacent structures, particularly in urban areas, and to prevent damage to adjacent
structures, and loss of lives and property is of the obligation. In the meantime, the use of storage
systems such as tensile inhibition (Anchorage) for some reasons such as high reliability,
flexibility, speed and ease of implementation are considered by civil engineers.
Recent research results and case studies show that the performance of containment walls in the
stabilization and consolidation of digging trenches can be as good as other conventional
methods, so that the lateral displacement of the wall based on the record of this type of
monitoring, mainly has been between 3/0 to 4/0 per cent digging deep. [1] In this paper, in
addition of describing the mechanism of using the inhibition of the stretching procedure for
stabilizing soil sampling pit, horizontal displacement containment under wall attached vertical
and lateral loads due to the complexity of the soil profile, numerical modeling of the actual
situation, in this study the behavior of gravity and lateral load in 13 meter excavation of walls of
commercial – residential project Habib by PLAXIS2D software in a two-dimensional form and
plain strain conditions with regard to the stage construction (Staged Construction) numerical
modeling is based on the actual conditions, and the results obtained from this modeling are
compared with the results of the monitoring (Monitoring) horizontal displacement behavior of
the different levels of containment wall height. The results show that despite the complexity of
the soil and limits on numerical modeling, there is good compatibility between the numerical
results and the amount of lateral deformation.
