Abstract: A MATTRESS CONSTRUCTION EMPLOYING A PLURALITY OF INDIVIDUAL AIR-TIGHT FOUNDATION UNITS INSERTED WITHIN THE INTERIOR OF A FOAM MATERIAL HOUSING IN A JUXTAPOSED RELATIONSHIP BUT WITHOUT BEING SECURED TO EACH OTHER OR TO THE HOUSING WALLS.

Abstract: A FOUNDATION STUDY WAS CONDUCTED TO DETERMINE THE SUITABILITY OF THE PROPOSED SITE FOR PLACEMENT OF THE SUBMERSIBLE TEST UNIT II (STU II) SERIES. THE PROPOSED SITE WAS AN AREA APPROXIMATELY TWO MILES SQUARE IN THE VICINITY OF 34 DEGREES 05.5'N, 120 DEGREES 43.0 W, SOME 14 MILES WEST OF SAN MIGUEL ISLAND, CALIFORNIA. EIGHT CORES WERE TAKEN TO DETERMINE THE ENGINEERING PROPERTIES OF THE SEDIMENTS IN THIS AREA. TO AID IN THE SITE EVALUATION, A BATHYMETRIC CHART WAS CONSTRUCTED USING DATA OBTAINED FROM THE PRECISION DEPTH RECORDER AND POSITIONING INSTRUMENTS ABOARD THE USS MOLALA. WITH THE RESULTING DATA FROM LABORATORY TESTS ON THE SAMPLES, COMPUTATIONS FOR BEARING CAPACITY AND SETTLEMENT WERE MADE. THE CALCULATED AVERAGE BEARING CAPACITY WAS 300 PSF. BASED ON THE APPLIED STRUCTURAL LOADING PRESSURE OF 110 PSF, THE TOTAL SETTLEMENT WAS CALCULATED TO BE 1.7 INCHES. STATISTICAL EVALUATION OF THE TEST RESULTS FORMULATED RELATIONSHIPS FOR VANE SHEAR STRENGTH AND BULK WET DENSITY THAT COULD BE USED IN SITE RECONNAISSANCE STUDIES. /ASCE/

Abstract: 1. Two types of segregation are encountered when placing moraine soil in a dam: partial separation of large fractions, boulders and pebbles, occurs in the upper, “ry”, part of the layer when constructing dikes; under the water the finer fractions, clay, silt, and sand particles, separate. Both underwater and above-water segregation can be controlled to a certain extent. 2. Segregation of moraine soil is most dangerous when placing fines-poor soil in thin layers: the boulders separated in the upper part (owing to the thinness of the water layer) can reach the base and form a lateral drain in the dam. 3. The ability of soil to separate into fractions can be used for concentrating it at the borrow pit or when setting up reserve dumps (Fig. 5). 4. When dumping under water there is an accumulation of the dispersed material, which can be used for connecting the earth structures with the concrete structures, for sealing the foundation, and for reducing seepage through the dam. 5. To overcome the removal of the separated fine fraction when placing soil on a base not cleaned free from a boulder pavement, intense placement of the soil is recommended or, if the rate is sufficient, a) simultaneous dumping of 10–30 m3 of soil, b) a decrease of the height of the dumped layer, c) placement of clay soil, d) clearing the foundation under the downstream cofferdam-dike. 6. At a head on the dam of up to 30 m the boulder pavement can be left in the foundation, if under it is dense moraine soil (or bedrock) and its thickness does not exceed 2 m.

Abstract: RESULTS OF IN-SITU FOUNDATION MODULUS TESTS AT THREE SITES OF DAMS IN TASMANIA ARE PRESENTED. THESE RESULTS ARE USED TO OBTAN A CORRELATION BETWEEN THE MODULUS OF ELASTICITY AND THE PHYSICAL PROPERTIES OF THE ROCK. SOME SIGNIFICANT DEPARTURES FROM THE CORRELATION INDICATE THAT THE TESTING PROCEDURE AND HIGH STRESSES IN THE ROCK MAY AFFECT THE MODULUS OBTAINED FROM THE TESTS. /RRL/

Abstract: For foundation settlement, support deformation, humidity and temperature change, crack types are analysed and preventive measures and remedies given. Principally for modern building.

Abstract: EXPERIMENTAL DATA ON THE DEVELOPMENT OF STRESSES IN A SOIL MASS BOUNDED BY A RIGID FRAME WITHOUT A BOTTOM PERTAIN MAINLY TO LABORATORY INVESTIGATIONS WITH SMALL-SCALE MODELS. EXPERIMENTAL INVESTIGATIONS ARE CARRIED OUT ON A LARGE-SCALE MODEL OF A CELLULAR RETAINING WALL WITH A HEIGHT OF 4.25 M (WITH INSIDE DIMENSIONS OF THE CELLS 1.55 X 1.55 M) CONSTRUCTED ON A NATURAL SAND FOUNDATION. THE MODEL IS FILLED WITH FINE GRAINED SAND OF NATURAL WATER CONTENT (5-6%) WITH A 30% CONTENT OF PARTICLES 0.5 - 0.25 MM AND 70% PARTICLES SMALLER THAN 0.25 MM; THE UNIT WEIGHT OF THE FILL AVERAGE 1.53 TONS/CUBIC M; ANGLE OF INTERNAL FRICTION, 30 DEGREES. CONSTRUCTION OF THE EXPERIMENTAL WALL DID NOT DIFFER FROM THE USUAL CONSTRUCTION PRACTICE: FIRST A STRIP FOOTING WAS CONCRETED AT THE SITE (WITH EMBEDDED SOIL DYNAMOMETERS), THEN THE FRAME OF THE MODEL WAS CONSTRUCTED OF FOUR READY-MADE, TWO-CELL HOLLOW BLOCKS AND FILLED WITH SAND. THE RESULTS ARE GIVEN OF AN INVESTIGATION OF THE STRESSES INSIDE THE CELLS (HOLLOW) AND AT THE FOOT OF THE WALL WHILE CONDUCTING THE EXPERIMENT WITH GRADUAL REMOVAL OF THE FOUNDATION SUPPORT ON THE CELLS' BASE, WHICH WAS ACCOMPLISHED BY TAKING THE SOIL AWAY FROM UNDER THE FOUNDATION. THE UNDERMINING PROCEDURE WAS SUCH THAT THERE WAS A UNIFORM SETTLEMENT OF THE STRUCTURE AND THE IMSTRUMENTS INSTALLED IN THE FOOT OF THE FRAME FOR MEASURING STRESSES WERE IN OPERATION AS LONG AS POSSIBLE. UNDERMINING IS PERFORMED IN STAGES; AFTER EACH STAGE OBSERVERS MEASURED THE STRESSES IN THE SOIL, TOOK THE LEVELS OF THE SURFACE MARKERS FASTENED ON THE FRAME, AND NOTED THE INCLINATIONS OF THE WELL. THE ARTIFICIALLY CREATED CONDITIONS IN WHICH THE STRESSES UNDER THE FRAME EXCEEDED THOSE PERMISSIBLE FOR THE GIVEN SUPPORTING SOILS ARE MENTIONED. /LCPC/A/RRL/

Abstract: 1,102,668. Foundation blocks. VIC HALLAM Ltd. 20, Oct., 1966 [21, July, 1965], No. 30947/65. Heading E1B. The lower cill 6 of a timber or other wall is secured to a prefabricated foundation block 1 of L cross-section by T-headed bolts 4 engaging an undercut metal channel 3 cast into the block. The block 1 is supported on a brick or other foundation 8 and acts as permanent shuttering for a poured concrete slab 7.
