|2. Guidelines for Soil Nailing Technique in Highway Engineering, MOSRT&H Research Scheme (R-86)|
|Date of Start|
|Scope and Objectives|
|(i) Appraisal of design and analysis methods for soil nailing with reference to some case study in India and abroad.
(ii) To analyze the various failure modes for soil nailing technology .
(iii) To analyze the construction methods for soil nailing.
(iv) Development of guidelines for different types of loading conditions including earthquake loading.
(v) Development of specifications for the applications of soil nailing technology in the field of Highway and Bridge Engineering.
(i) Appraisal of design and analysis method for soil nailing technique will be done after a thorough study of state of pratice followed in different countries. A state-of-art report and state of practice report will be prepared based on the above study. The codal provisions in BS:8006 (code for reinforced soil structure) shall also be examined.
|This study will help in evolving guidelines for different types of loading conditions including earthquake loading for different soil conditions and drainage conditions. It will also help in development of specifications for the application of soil nailing technology relate to Highway and Bridge Engineering for different soil conditions and drainage conditions.|
|Soil nailing technique has number of applications in the field such as stabilization of cut slopes, construction and retrofitting of bridge abutments, construction of tunnel portals in steep and unstable rock strata. This technique is fast becoming the preferred method of construction for soil retaining wall due to its cost effectiveness and easy method of construction. The effective formulation of guidelines and specifications for soil nailing technique would be of great help for Highway Engineering.|
