a bridge at the crossing on a deposit of saturated interbedded deltaic sand, lacustrine silt, and clay, in order to minimize seepage, foundation and slope instability problems.
835248 COLLISION PROOF CAISSONS CARRY HOBART LINK New Civ Engr, N556, 23 June 1983, P26-27 Describes construction of the underwater foundations for the Bc~en Bridge, Hobart, Tasmania, designed to make it impregnable to ship collisions. The 976m long bridge is to be s u ~ e d on 1.2m thick caissons, built within a 14m diameter dewatered reinforced concrete cofferdam.

Tenier, P; Mcrlier, P Can Geotech J, vIg, N3, Aug 1982, P396-400 Concentrated loads are not properly taken into account in simple methods of slope stability analysis such as Bishop's method. It is proposed to replace, in Bishop's equations, amy surchsrge by a statically equivalent stress distribution of the failure surface. An application of this technique is l~esented in the form of the Optimization of a slope stabilization by tie-backs.
8352~9 HIGH WOOD RESERVOIR - FLANNING, DESIGN AND CONSTRUCTION Pasley, N C Water serv, V87, NlO~3, Jan 1983, Pll-18 Site investigation, a study of the site geology and numerous soil tests were carried out. Results from these tests indicated a cohesive, inorganic, medimn to highly plastic soil with low coefficients of compressibility and vol~me change. It was decided to construct the reservoir with concrete floor and walls. This initial design was not able to provide a large enough factor of safety against sliding and lo~ering of the water table was considered essential to improve ground conditions.

The results irdicate parameters which are important in the variation of the safety coefficient of the slope: intensity of rainfall, quantity of the rain that falls and absence of rainfall over a long period.
835250 MEASUREMENT OF PERFORMANCE OF OFFSHORE PILED FOUNDATIONS - A REVIEW St John, H D Ground Ergng, VI6, N2, March 1983, P24-30 Discusses aspects of offshore pile design where greater understarzling is required: ultimate axial loads for piles in clay and in sand, the effect of the type of applied load on pile response, the influence of lateral loads on axial pile response, the interaction between the structure, footings and piles, the behaviour of piles under sustained temsion, amd pile behavlour in soils other than clays and sands. An historical review of full-scale testing of piles and piled structures is then given. The meas~m~ment of interface stresses on driven piles is examined in detail.

The slope failure, caused by a combination of sliding and toppling failure, was much shallc~er than expected and did not affect the instruments.

Darcy's equation amd ur~att~ated-flo~ theory are used to calculate flow through earth linings that are placed in pomds or channels to reduce seepage. The l~OCedt~e uses the relation between tmsat1~ated ~ v l i c comdt1~tivity and the l~esm~e head of the vxxl~rlyimg material. The method allows selection of a liner that will keep seepage below a certain maxim~n limit.
