Abstract
This chapter presents application of geotechnical instrumentation and observation methods in the construction projects during the last few decades. Geotechnical instrument to monitor change in ground and groundwater conditions and pressures, stresses, deformations etc., is monitored during the construction of the infrastructures. In the following sections, case studies written by engineers who were intensively involved in the implementation of such projects especially in geotechnical and geotechnical instrumentation aspects of the works are presented. Geotechnical instrumentation has been utilized in the following construction projects:
-
1.
Land reclamation
-
2.
Ground Improvement
-
3.
Landfill
-
4.
Dam and embankment
-
5.
Highway, railway and bridge
-
6.
Excavation
-
7.
Tunnelling
-
8.
Deep foundation, but not limited to
In this chapter, a few selected case studies on application of geotechnical instrumentation in land reclamation and ground improvement project, slope stability project, excavation project and tunnelling project are presented.
