3.9 Technical summary for 200m level CFRD (2)Integrated techniques for deformation control including: Utilizing rock of high compressive strength Defining reasonable graduation and void ratio Decreasing deformation modulus difference between down and upstream rockfill Employing higher degree of compaction Dam body filling rising evenly Adopting pre-settlement measures Preloading by water storage with temporary section - 30 -
3.9 Technical summary for 200m level CFRD (3)Numerical results generally reflects stress and deformation response of the dam, settlement agree well with the measured value, while lateral displacement has lower accuracy. And difference still exist between parameters from back-analysis and tests. ( 4 ) Experiences from 200m high CFRD provide technological reserve for construction of 300m high dams. (5) Deformation control techniques from 200m high dams are instructive and meaningful to construction of 300m high CFRD. - 31 -
