The t h e o r y for soil comsolidati~n by electro-osmosis is presented snd extended to two special cases that may be useful in t h e field, i.e., electrode reversal to prOduce more uniform water content d e c r e a s e and strength increase between electrodes and superposition of consolidatimm by electro-osmosis onto that due to direct load. It is shown that the Terza~hi consolidation equation descries the rate of consolidation so long as the voltage distr~butiom remains comstent with time. Experimental results show reasonable conformity with the theory for the case where soil properties remain essentially constant during eleotro-osmosis consolidation. Test results support the electrode reversal technique as a moans for accelerating comsolidation by electro-osmosis and for establishment of uniform properties between electrodes. Auth.

This rel~rt ;resents the results of a prel~m~nary engineerlng geology study of parts of Los Altos Hills s~d Stanford University lands. The purpose is to describe the natural geologic conditions, to delineate areas which may present problems to develolm~ent, and to pro. vide a basis for land.use plamnin~ of the area. The report presents technical data only and does not consider social or economic considerations which should also have important bearings on the ultimate land use. Auth.

The finite element method has been an important tool for solving engineering and related structural problems for two decades. Recently, its use has spread to problems in the geosciem~es. A finite element model is specifically developed to determine the amount of restrained rebound that occurs in the earth when an ice sheet from the earth's surface molts. Auth.

First the deflected shape of the structure is represented as the sum of two components: one due to flexural cantilever action and one due to shear-flexure cantilever action. The natural frequencies of the latter two systems are then combined in Dunkerley's for~slla to yield the approximate frequency of the structure. Auth.
