Calculation of Pile Foundation <\/strong><\/h2>\n\n\n\n

The pile code consists of four parts.They are<\/p>\n\n\n\n

Part 1: Concrete piles<\/p>\n\n\n\n

Part 2: Timber piles<\/p>\n\n\n\n

Part 3: Under reamed piles<\/p>\n\n\n\n

Part 4: Load test on piles<\/p>\n\n\n\n

Out of these Part 1 consists of four section<\/p>\n\n\n\n

Among these Calculation of Pile Foundation ,<\/strong><\/p>\n\n\n\n

Section 1: Driven cast in situ concrete piles.<\/p>\n\n\n\n

Section 2: Bored cast in situ concrete piles and<\/p>\n\n\n\n

Section 3: Driven precast concrete piles are revised in 2010<\/p>\n\n\n\n

Some of the important changes in the code are highlighted as follows:<\/strong><\/p>\n\n\n\n

1.  Definitions of\nvarious terms have been modified as per the prevailing engineering practice.<\/p>\n\n\n\n

2.  Minimum grade of\nconcrete to be used in pile foundations has been revised to M25.<\/p>\n\n\n\n

3.  Design parameters\nwith respect to adhesion factor, earth pressure coefficient, modulus of\nsubgrade reaction, etc, have been revised to make them consistence with the\noutcome of modern research and construction practices.<\/p>\n\n\n\n

4.  Minimum dia of\nbored cat in situ pile have been changed as 450mm based on following\nparameters:<\/p>\n\n\n\n

Clear cover over reinforcement <\/strong><\/p>\n\n\n\n

Cl.6.11.4 50×2        \n= 100mm<\/p>\n\n\n\n

Dia of vertical bar minimum <\/p>\n\n\n\n

Cl.6.11.4 12×2             \n= 24mm<\/p>\n\n\n\n

Helical reinforcement minimum <\/strong><\/p>\n\n\n\n

5.  Provisions for\nspecial use of large diameter bored cast in-situ reinforced cement concrete\npiles in marine structures have been added.<\/p>\n\n\n\n

6.  Procedures for\ncalculation of bearing capacity, structural capacity, factor of safety, lateral\nload capacity, overloading, etc, have also been modified to bring them at par with\nthe present practices.<\/p>\n\n\n\n

7.  Minimum time of\ncuring before handling of precast piles has been modified.<\/p>\n\n\n\n

8.\u00a0 Provisions has been made for use of any established dynamic pile driving formulae, instead of recommending any specific formula, to control the pile driving at site, giving due consideration to limitations of various formulae.<\/p>\n\n\n\n
