861204 Foundation performance of very old structures Handa. S C Proc International Conference on Case Histories in Geotechnical Engineering, Rolla, Missouri, 6-11 May 1984 V1, P201-208. Publ St Louis. Geotechnical Engineering, 1984 The subsoil conditions at the site, the type of foundation, construction technique and performance over very long periods are examined for the Taj Mahal and Qutb Minar, India. The damage that has occurred and repairs and strengthening required are described.
861205 Philip Morris Corporate Headquarters Building Ciancia, A J; Horn, H M Proc International Conference on Case Histories in Geotechnical Engineering, Rolla, Missouri, 6-11 May 1984 V1, P209-216. Publ St Louis: Geotechnical Engineering, 1984 The temporary support of three city streets, a subway tunnel, and a high-rise office tower during the construction of the Philip Morris Corporate Headquarters Building, New York, USA, is discussed. The results of an extensive field exploration program, consisting of test borings, probes, and geologic mapping were evaluated for the design of temporary support systems, ie, rock anchors and rakers. Borehole extensometers and conventional optical survey techniques were successfully used to monitor movements of the adjacent structures during demolition of a building that occupied the site. After an extensive geologic mapping program and a complex series of borings, the rock foliation was found to be favourably oriented. allowing the footings to be founded in rock above the subway tunnel.
861206 Chimney foundation on drilled piers Chung, K Y C; Cundy, L D Proc International Conference on Case Histories in Geotechnical Engineering, RoUa, Missouri, 6-1! May 1984 VI. P217-221. Publ St Louis: Geotechnical Engineering, 1984 The design and comparison of the predicted performance to actual responses of a drilled pile foundation supporting a 305m high chimney is described, in order to evaluate laboratory and empirical side friction and end bearing criteria used in the pile design. Using results of a subsurface exploration program, and considering vibration effects on nearby structures, a foundation system was designed consisting of 38 drilled piles capped with a concrete mat. Each pile was designed to support a maximum compressional load of 1,362 tons. The side friction and end bearing capacity were analyzed from data accumulated under construction and service conditions. A comparison of this analysis with criteria suggested by others indicated compliance with accepted design standards.
861207 Design considerations and long-term performance of a building foundation in clay Bauer, G E Proc International Conference on Case Histories in Geotechnical Engineering, Roila, Missouri, 6-11 May i 984 V1, P229-234. Publ St Louis." Geotechnical Engineering, 1984 Based on the results of full-scale footings tests, spread footings were used instead of end-bearing piles to support a four storey building extension. Five prototype footings were instrumented and the settlement behaviour was monitored over 13 years.
Special construction procedures had to be empio~ed to achieve compatible differential settlements between the individual footings and the adjacent existing building. A u t h
861208 Monitoring and performance of a bridge abutment Felio. G Y; Bauer, G E Proc International Conference on Case Histories in Geotechnical Engineering, Roila, Missouri, 6-11 May 1984 VI. P235-239. Publ St Louis. Geotechnical Engineering, 1984 The bearing capacity and settlement of footings in granular fill was examined by monitoring the performance of a bridge whose end spans are supported by abutments with spread footings in a granular approach fill. Surface settlements, earth pressures at the back of the abutment wall and the base of the footing and horizontal and rotational movements of the abutment have been studied.

Publ St Louis. Geotechnical Engineering, 1984 The Bridge River Powerhouse No. I was constructed between 1946 and 1950 on the north shore of Seton Lake, British Columbia, Canada. High artesian pressures below the dense till foundation caused ground cracking in 1950 which resulted in movement of the powerhouse. The causes of cracking, 33 years of powerhouse instrumentation data and remedial measures carried out to stabilize the powerhouse are reviewed.

Publ St Louis: Geotechnical Engineering. 1984 A case history of the main events which occurred in the design and construction of the Ju'Aymah Pipeline Trestle is presented. This offshore jetty was founded on calcareous rocks and sands and clay layers, and a drilling and driving procedure using oversize holes was adopted. The load testing program is discussed. Some 1500 prestressed concrete cylinder piles, were successfully installed.
861211 Non-negative skin friction piles in layered soil Lee, S L; Sithichaikasem, S Proc International Conference on Case Histories in Geotechnical Engineering, Rolla, Missouri, 6-11 May 1984 V1, P285-288. Publ St Louis. Geotechnical Engineering, 1984 Pumping of water from sand layers in the substrata of Bangkok can lead to ground subsidence. Piles driven into these layers are subject to negative skin friction. To overcome differential settlement, piles may be driven into a second sand layer with much lower subsidence. Steel pipe piles coated with a non-negative skin friction (NF) layer can be used to combat the increase in negative skin fricion for piles driven into the second sand layer. The design concept in assessing the pile length, carrying capacity, settlement, construction control and load tests under these special conditions are discussed.
