<p>Continuous monitoring of subsurface ground movements is accomplished with in-place instruments utilizing automated data acquisition methods. These typically include TDR (Time Domain Reflectometry) or assemblies of several servo-accelerometer-based, electrolytic ...

<p>This paper describes the successful construction of new highway embankments over soft soils alongside existing high-traffic volume highways in the Greater Vancouver area of British Columbia. Highway 10 and Highway 15 intersect at Cloverdale in the City ...

<p>In this study, firstly, a series of field monitoring data on earth pressure in soft clay, hard clay and sand ground are analyzed respectively. In the soft clay ground, the earth pressure fluctuated with backfill grouting pressure at first, it settled down ...

<p>This paper describes the construction of a 40m multi-propped deep excavation in the downtown area of Shanghai, China and the interpretation of the monitoring data. The entire excavation was 263m in length, 23m wide and 38&ndash;41m deep. The excavation ...

<p>Twenty papers accepted for publication under IS-Shanghai 2008 Session 3 on Case Histories are classified and summarized. Papers deal with open pit excavations, ground improvement, tunnels, monitoring systems and impact on surroundings, most of them related ...

<p>This manual describes the operational safety procedures to be followed when using Nuclear Moisture &ndash; Density Gauges under the control of the Geotechnical Engineering Bureau, New York State Department of Transportation. This manual must be used in ...

Soil moisture monitoring systems involving correlations with soil dielectric content measured using WCR (water content reflectometer) probes are susceptible to lightning-induced errors during field monitoring programs. These errors must be understood and corrected ...

Population growth frequently causes expansion of urban populations and associated transportation facilities onto formerly uninhabited slopes, where naturally occurring and constructed rock faces present potential hazards from rock fall and rock face instability. ...

A geosynthetic-reinforced soil (GRS) system was constructed to support the shallow footings of a two-span bridge and the approaching roadway structures. Construction of this system, the Founders/Meadows bridge abutments, was completed in 1999 near Denver, ...

This thesis presents the application of Time Domain Reflectometry technology in nine case studies. Presented in detail are cable and grout installation techniques, data acquisition instrumentation and autonomous real time monitoring of soil deformation using ...
