Abstract:

Hydraulic structures are planned and built to behave safely during their design period. For understanding and to study the behaviour of concrete structure, instrumentation in the foundation and the body of structure is very much essential. With the continuous service, structures are developing cracks and joints due to concentration of stresses. These cracks and joints are required to be monitored, analysed and find out its effect of the safety of the structure. There is no standard method for selection of instrument location for measuring crack dimensions. However, instruments can be installed according to anticipation and assumptions of cracks during design. To study the variation of cracks in x, y and z directions, 2D and 3D crack monitors are usually installed across the cracks. Cracks are random discontinuities whereas joints are predetermined discontinuities. For crack/joints movement monitoring, usually, crack width and relative slip is measured. This paper discusses the comparison of the pattern of relative movement of crack in 2-dimensional (2D) and 3- dimensional (3D) directions by using 2D and 3D crack monitors data in Y-direction (across the crack) or closing and widening of crack in the powerhouse structure of 92 m high Rihand Dam, Uttar Pradesh, India.
