Our tunnel and dam project experiences are: From program management, planning, and design, through installation, monitoring, and evaluation, GZA provides Geotechnical instrumentation and Geotechnical instrumentation systems to owners, engineers, and contractors on projects above and below ground.
Limited geotechnical instrumentation may be needed for simple projects but the demands on geotechnical instrumentation and monitoring can be very demaning for critical projects such as tunnels, slopes, and excavations next to sensitive structures.
Automated data acquisition systems Deformation of soil and rock Loads on ground support systems Stress and deformations of tunnel lining systems Soil and rock pressure Pile driving dynamic load capacity and stresses during driving Groundwater pressure Settlement and cracking of buildings Real-time web based data presentation We also perform pre-construction building surveys prior to blasting or other vibration producing construction activities.
Geotechnical instrumentation systems are essential in helping project teams understand the behavior resulting from various underground construction activities. Geotechnical instrumentation and monitoring are essential for the successful completion of a geotechnical projects. Workshops Geotechnical instrumentation - monitoring Geotechnical instrumentation refers to to the instruments used to monitor geotechnical projects or sites requiring such monitoring.
Our expertise with various types of geotechnical instrumentation has helped our clients execute various tunneling operations efficiently with minimal impact. Public Works Projects GMU has an extensive resume for geotechnical instrumentation and monitoring of highly visible Public Works projects throughout California.
The quality of data in more recent projects tends to be better since computers have facilitated data acquisition and archiving. In very few projects strain gages and embedment gages were used to deduce moments and axial forces in the slurry wall.
For example, in Boston, the majority of the inclinometers were installed within the diaphragm walls while in Chicago they have been installed within the retained soil. Monitoring strategies are not significantly different from city to city but the extent of instrumentation does depend on local practices.
Select developments where instrumentation was utilized include: Thus, inclinometer deflections have been more widely used for comparisons between cases due to their availability in almost all the archives. Tunnel and Dam Projects To monitor the effects of tunneling operations, GMU provides geotechnical and structural instrumentation services.
Generally, the quality of the available instrumentation was dictated by the project requirements. Inclinometers, piezometers and optical surveys have been used to monitor the majority of the projects compiled in this database.
Earth pressure cells have been used only in test programs.
Sometimes, single point extensometers have been used to measure subsurface settlements, but multipoint borehole extensometers have only rarely been used.
