Abstract
A Major port in India had six cargo berths and a seventh one was to be added to cater for the heavy cargo traffic. The top layer of the soil along the berth was 20 m thick soft and sensitive marine silty clay with an average shear strength of 2 tons/Sqm. The design provided for a berth 342 m long. It had a quay and transit area supported on 750 mm diameter bored piles which was followed by open stacking ground 60 m wide, to be preconsolidated by sand drains. Finally it had a paved unconsolidated area 120 m wide. The design was also provided with a defense dyke and a filled up area to allow the machinery to work in the dry. Soon after start of piling a sudden settlement of the soil was observed in a length of about 40 m. The defense dyke also bodily shifted towards the sea. After a period of about seven months there was a serious foundation failure. Investigations were carried out into the causes of failure. The paper describes the details of investigations and final remedial measures taken.
