Surcharge load= 10 KN/m2
Water depth =20m
Water density=9.81 KN/m2
Min. fluid density=5 KN/m2
Excavation = 7.5
Moment =751 KN/m2
Moment capacity =901.5/.8=1127 ok
1- The two alternatives of protection are goal for the required purpose .
2- The using of piles requires less time Of the excavation
3- The distance between the adjacent piles in the row is recommended to be less than 3*D
4- Piles are recommended to connect on the top y means of a reinforced concrete beam.the following conclusions can be made :
