Movement within Large Fills, Ridge Route Project

摘要

The development of instrumentation for measuring the magnitude and direction of horizontal and vertical movements within embankments of up to 240 feet in height and the measurements obtained during construction are reported. Revisions to design of instrumentation and protection of reading devices are discussed. Data obtained during and immediately following construction of two embankments on I-95, 12 miles north of Castaic in Los Angeles County, are presented and discussed. The use of cylindrical steel instrument shelters proved to be entirely effective in preventing damage to instrumentation placed on embankment slopes. Recommendations for improvement in design of instrumentation and reading methods are discussed. (Author)
