The Construction Of A New Harbour At Nørre Sundby, Jutland

the harbour deepened. An examination of the bottom showed that not until reaching the depth of 60 to 70 feet a foundation could be in any measure secure. Above these depths the extensive layers consisted of a soft, sliding mass. The plans, therefore, ne- cessarily were to be directed al finding a construction, that could stand by ils own weight, without anchorage, resting on a base that by its con- sistency would prevent a dis- placement; all of which had to be done for the proportio- nately small amount that could be provided. In regard to the main con- struction, it was considered best, first to dig away the soil soil to the depth of about 43 feet, and lill up with a heavy sand foundation, upon which was erected a construc- tion of sinking-boxes of rein- forced concrete. The details of this construction are shown on the accompanying plan. The boxes are about 32 feel long, 83/< feet broad at the top, and 163/4 feel broad at (he base, the height is about 25 feet. The superstructure consisted similarly of rein- forced concrete, and is clo- sed on the lop by a granite coping stone and provided
