Reinforced grout j-hook hybrid anchor soil nail system for slope stabilization / Ir. Ts. Mohammed Fadhil Jamain

Malaysian practice on soil nail design is mostly still adopted conventional passive soil nailing system. Unfortunately, there are some limitations of this conventional design concept when many failures reported involved the conventional passive system. Hence, a wider understanding of the soil nailing behaviour is necessary, together with innovation in design. Therefore, this research focused on soil nail pull-out strength based on laboratory scale test, prototype field test and full-scale test on actual project and finite element modelling comparison. The objectives of this study are: (i) to develop new design concept of Reinforced Grout J-Hook Hybrid Anchor (J-Hook) soil nail; (ii)to assess the applicability of the concept by running lab model; (iii) to determine the constructional viability of the system by doing field installation and in-situ pull-out test;(iv) to determine the performance of the J-Hook soil nail in actual slope strengthening project; and (v) to validate soil nail modelling by using Simulation software.
