SP013 – Safety Evaluation of a Slab and Buttress Dam

ABSTRACT:

This paper portrays the security assessment and improvement of remediation alternatives for Clover Dam, a 28 m high piece and brace structure arranged in the snow capped district in upper east Victoria, Australia. The survey was especially testing thinking about the unpredictability, age and split state of the dam structure, which required the advancement of an examination strategy for this sort of dam. Finished in 1953, Clover Dam is one of five dams in the Kiewa hydroelectric plan. The 76 m long dam includes a 45.7 m since quite a while ago secured piece and brace segment, upheld on every projection by cement gravity areas. The audit was attempted because of extreme breaking happening since the mid 1970s furthermore, in light of the fact that a nitty gritty structure survey had not been attempted since its development.

Current rules for the wellbeing survey of existing dams give minimal itemized data on section and support dams. Subsequently, a technique was produced to dissect Clover Dam. This philosophy could likewise be connected in the survey of this sort of dam when all is said in done, and is right now being utilized for wellbeing appraisals of three other piece and support dams. This paper centers for the most part around the dam basic appraisals embraced amid the wellbeing audit. The auxiliary investigations included 3-D limited component examinations for warm, static and quake stacking. The result of the audit was that both the gravity and brace parts of the dam don’t meet current plan gauges. The improvement of practicable remediation alternatives was confused by the operational limitations and the confined access to those zones inside the dam where therapeutic works were required.
