This research was conducted by micropile method in order to study the handy and non-aggregate soil on the east side of the Kan River, in west of Tehran. In this area a tent structure is located on a relatively deep gable roof of coarse grain non- aggregate soil (handy soil), in around of this structure, deeply cracks have been observed. Survey and study of existing cracks around this structure indicate the presence of non-aggregate surface soil subsidence and unstable gable roofs, micropile method is used for control subsidence and structure movement as well as soil improvement. These areas located in river deposits and for geotechnical studies 31 boreholes and 10 handy wells have been drilled. Types of soil are GC and SC. With analyses by GeoStudio software, micropile implementation for stability of gable roof and stabilizing structure in the entire system was confirmed. After implementation of design, the gable roof movement and subsidence was controlled by continuum camera and resulted stop movement and general subsidence of gable roof.
