| 1 | It covers provisions on design and construction of vertical drains used for improving the ground such that the consolidation under preload is accelerated resulting in improvement of ground to carry envisaged loads. | |
| 2 | a) The standard was previously brought out as a guideline standard as the experience of ground improvement techniques in the country was limited. With lot of experience gained over the years, it has been decided to bring out the revised standard as a code of practice standard. The title of the standard has been changed accordingly. b) Definitions of various terms have been modified as per the prevailing engineering practice. c) Quality control and test requirements for prefabricated vertical drains have been incorporated. d) Smear effect has been included in design procedure. e) The factor of safety against possible slip or bearing failure has been reduced to 1.2 to be consistent with other Indian standards. f) Vacuum consolidation method has been included. g) Instrumentation and monitoring has been included. | |
