PERFORMANCE AND DESIGN OF SLURRY WALLS IN SOFT CLAY

Extensive field tests on instrumentation, construction control, etc. were carried out on the performance and design of slurry trench walls in soft clay. These tests were designed to establish criteria and methods for evaluating the stability of slurry-filled trenches in soft day, to acquire data on the practical aspects of such construction, and to determine the performance of slurry-trench walls as earth-retaining structures. This article documents some of the extensive data that was gathered. The study found that there were on particular problems associated with construction of slurry-trench walls in soft clay. It is possible to construct such walls in soft clay with only clean water as supporting fluid. The special use of cross-lot walls to prevent bottom heave failure functioned well for two tunnel projects that were studied. For economical design, it is necessary to apply analytical methods that account for the interaction between soil-wall and support system and the actual sequence of excavation and installation of supports. It was found that earth pressures increased with time after completion of construction and approached the at-rest condition.
