Title: SOILS INVESTIGATION FOR THE RAINY LAKE CAUSEWAY
Accession Number: 00228575
Record Type: Component
Abstract: THE RAINY LAKE CAUSEWAY IS ABOUT 2.8 MI LONG AND CONSISTS OF ALTERNATING EMBANKMENTS AND BRIDGE STRUCTURES. AT ITS LOCATION, WATER DEPTHS ARE UP TO 50 FT AND THE PREDOMINANT SOIL STRATUM IS A GENERALLY NORMALLY LOADED VARVED CLAY WITH A MAXIMUM THICKNESS OF ABOUT 50 FT. THE PAPER DESCRIBES IN DETAIL THE SOIL CONDITIONS ENCOUNTERED. BECAUSE OF THE SOFT NATURE OF THE CLAY, STRUCTURE FOUNDATIONS EXTEND TO BEDROCK. CONSTRUCTION OF EMBANKMENTS, HOWEVER, REQUIRED SPECIAL TREATMENT FOR CONSIDERATIONS OF STABILITY AND SETTLEMENT. IT WAS CONCLUDED THAT TOTAL DISPLACEMENT OF THE CLAY BY THE EMBANKMENTS WAS ESSENTIAL AND BLASTING TESTS WERE CARRIED OUT TO DETERMINE HOW THIS COULD BE EFFECTED. IN ADDITION, BORINGS WERE MADE THROUGH AN EXISTING RAILROAD FILL. THE RESULTS OF THE BLASTING TESTS, THE METHOD OF CARRYING OUT BLASTING IN PRACTICE, AND EMBANKMENT CONSTRUCTION ARE DESCRIBED. THE USE OF BLASTING TO REMOLD THE CLAY TO THE EXTENT REQUIRED TO PERMIT FULL DISPLACEMENT BY ROCK FILL, WAS FOUND TO BE EFFECTIVE IN PRACTICE. /AUTHOR/
