Graphical solution for sheet pile embedment. Technical note
197A To determine the potential use of old motor tyres as soil reinforcement elements, work was carried out to: (1) study the behaviour of the reinforced soil, (2) study the mechanical characteristics of the tyres, (3) study the adherence between the soil and the tyres and (4) study the structural design. A description of a 10m long, 5m high experimental wall is included.

A three dimensional analysis is presented for a diaphragm wall in which arching effects in the soil surrounding the slurry support trench of the wall is taken into account.

The most important factors contributing to earthquake damage in buildings are examined based upon extensive statistical analysis of building damage in 25 earthquakes. The factors include foundation material, site effects, building quality, regularity or symmetry of the building, and the orientation of the building in relation to the predominant ground shaking.
A design method for anchored bulkheads in sand based upon a computational pressure diagram (CPD) is presented. The CPD has been developed from use of the conventional free earth support method.
845303 Graphical solution for sheet pile embedment. Technical note Masih, R J Geotech Engng Die ASCE 11110, NGT4, April 1984, P534538 A graphical method using a trial and error approach is described for obtaining the embedment depth of sheet piles. The soil pressure may vary linearly or nonlinearly with depth.

Typically 45% cement is added with the appropriate amount of water for the particular application. Following a successful pilot programme the material was used to fill a mile long trench at the Belle River Power Plant. The material's light weight and strength make it ideal for reducing settlement when fill must be placed on soft ground.

845308 Stress fields and subsurface crack propagation of single and multiple rook indentation and disc cutting Lindqvist, P A Rock Mech Rock Engng V17, N2, April-June 1984, P97-112 Indentation stress fields of one- and two-point loads applied on an ideal elastic half-space are presented. Laboratory observations, although few, are in surprisingly good agreement with long median and cone-type tensile cracks predicted by normal principal stresses. Results indicate that simultaneous loading by multiple indenters offers a possibility partly to control the direction and length of such cracks. This suggests the development of new cutter configurations with a possible increase in efficiency, as compared with present rock boring and rock cutting practice. A simple fracture mechanics calculation of the length of subsurface cracks is performed by applying indentation fracture studies of ceramics. Results demonstrate the influence of material parameters such as fracture surface energy, hardness and elastic constants. Auth.
