Behavior of foundations using driven vertical and inclined piles under horizontal loading
67A The results of 3 separate settlement measurement programmes for raft foundatmns of mulustorey braidings m stlffunsaturated clays are reported In 2 of the 3 cases, settlement predlcuons based on various methods were compared w~th observations Good agreement was found between measured and predicted values, w~th httle d~fference m the pred~ctmns from various methods The borehole extensometer techmque was found to be very efficient m the measurement of layer compression and overall settlement A s~mple alternatwe procedure for settlement pred~cuon that can account for layered softs and raft stiffness ~s demonstrated
842232 Shallow foundations on frozen soil: creep settlement Ladany~, B J Geoteck Engng Die ASCE V109, NGTI 1, Nov 1983, P1434-1448 After reviewing all presently available mformatmn on the creep settlement of shallow foundauons resting on frozen sods, it ~s concluded that some proposed theoretical methods have potentml for predicting settlements when their mare source is d~stort~onal creep. Much less ~s known about the prediction of settlements on relatively warm frozen soils w~th large quanttt~es of unfrozen water, where hydrodynamic consohdat~on and volume creep are the cause of a large proportmn of the settlement 28 refs

842234 Investigation of the engineering properties of a dam foundation containing gypsum seams. Technical note Chen Fengxmng, Wu Mmglmng Rock Meek Rock Engng V16, N4, Not, 1983, P275-280 A series of laboratory and m s~tu tests were carried out at Longmen Dam m order to investigate the composmon, solubdtty and leaching characteristics of gypsum seams m rock formatmns, as well as their effect on the strength and deformation properties of the rock masses
842235 Construction experience with industrial structures on soils prone to slump-type settlement in the Tadzhik SSR Gahtskn, V G, Musaelyan, A A, Popsuenko, I K, Vflfand, A G Soil Mock Found Engng VI9, N1, Jan-Feb 1982, P1-5 The Yavansk Electrochemical Plant, Tadzhlk, USSR is under construction on loess-hke, clayey sods and ioesses hable to slump type deformations Settlement development was variable due to seasonal fluctuation of the water table and loading conditions of the foundatton. The greatest absolute settlements, their relatwe nonumformlty, tdtmg and warping have been observed during the loading of the four reservoirs It is concluded that cyhc loading-unloading of different reservoirs and containers dunng watert~ghtness testing ~s an effective means of reducing the nonumformity of their settlement and stabdlzmg beds composed of highly compressible or saturated loess soils

Using the results of a range of field tests on pile columns and driven pdes, tables are presented from which K can be assigned for various soil types and pde lengths of 2-4m

P43-48 The construction of two ten storey braidings on pde foundations was investigated to estabhsh operating condit~ons and load distribution among the pdes Pdes, 30era X 30cm m sectmn and 11-12m long were driven rata Quaternary alluvml deposits and pile loading and settlement observed over 3 years until complete foundation settlement was estabhshed It ~s concluded that pde loads should be calculated on the basts of a three dimensional analysis which mcludes the superstructure, foundauon and sod base
