An Overview of the Development of the Yeywa Hydropower Project, Myanmar
The 790 MW Yeywa Hydropower Project is located on the Myitinge River approximately 50km southeast of Mandalay in central Myanmar. The Project comprises of a 134m high RCC dam with a power station located on the left bank at the foot of the dam and an ungated spillway located in the central section of the dam for flood water discharges. Two concrete-lined river diversion tunnels are located in the right bank; one of which will be converted into a bottom outlet. During the design of an RCC dam it is necessary to try to minimize the interferences to the RCC placement in order to achieve rapid construction. One of the features of the dam body at Yeywa is the use of an integrated cofferdam to protect the site during the potentially high floods. The dam body has been split into a number of separate placements to ensure continuity of construction particularly during the flood seasons. Planning of the sequence of these placements was required at an early stage of the dam design. The paper provides an overview of the Project development and design and the investigations during the search for a natural pozzolan; there is no fly ash in Myanmar. It includes a brief description of some of the key issues involved in the Project implementation, this being carried out under the rather unique conditions that exist in Myanmar during the construction of a major Project such as Yeywa HPP.
