Study of Construction Material Properties for TSQ-I Concrete Faced Rockfill Dam

This paper presents the main test results of the construction material for the Tianshengqiao-1 concrete faced rockfill dam,which is 178 m high Based on the basic tests of the rockfill material the author has studied the following subjects:a the test scale and its effect on the engineering properties of the rockfill material to propose an initial control limit of the simulated material;b the laboratory test method of simulating in-situ vibration compaction, the control criteria and the field roller compaction parameters;c the permeability,the permeability stability and the filter effect of the cushion material with various gradation to propose an optimized gradation range of the cushion material to meet the design requirement;d the compressive deformation and its adaptability of the cushion material and the rockfill material; and e the stressstrain characteristics of the cushion material and the rockfill material with different stress paths The test and study results are systematic and comprehensive, providing reliable basis for design of the Tianshengqiao-1 concrete faced rockfill dam and are applicable for other hydropower projects of this kind
