Numerical modelling of construction and impoundment of the Romaine-2 Asphaltic Core Rockfill Dam (Québec, Canada)

Construction progress and quality are two important objectives in the construction of high core rockfill dam. It is of great significance to evaluate their control effect comprehensively. In this paper, the progress and quality of high core rockfill dam construction management are the study objectives. in order to achieve the real-time control of coupling them, the comprehensive evaluation method for the quantitative analysis of their complex relationship is proposed. Based on the comprehensive analysis of the mechanisms of the influence related factors in the construction process, the comprehensive evaluation index system of the high core rockfill dam coupling construction progress and quality is designed ; the comprehensive evaluation index data acquisition process is analyzed; the comprehensive evaluation method for the high core rockfill dam filling unit is put forward. finally, a comprehensive evaluation of high core rockfill dam filling unit model based on TOPSIS is established. Engineering examples show that this method plays a guiding role in real-time control of coupling high core rockfill dam construction progress and quality.

Core Rockfill Dam

Rogun dam is a 335m high clay core rockfill dam which will be constructed on Vakhsh River in Tajikistan. Originally, two diversion tunnels with similar geometry were designed for discharging the seasonal floods, up to 3290m3/s. River diversion was carried out in November 1987 and a 45m high rockfill cofferdam was constructed. However, because of two collapses in the diversion tunnels, the cofferdam was overtopped in May 1993. Reconstruction of these tunnels started in 2009 and the collapsed areas were repaired. Nowadays, the design of complementary rehabilitation including new concrete lining for those parts of the tunnels will be used as tailrace tunnels are underway. The present paper describes the present conditions of diversion tunnels No. 1 and 2, explains the procedure used for the structural design of these tunnels, and presents the results of such design.
