Research and Application of Key Technologies for the Construction of Cemented Material Dam with Soft Rock

In order to safely and efficiently use soft rock aggregate cemented dams in red bed regions promote the development of widely sourced sand gravel dam materials, Jinjigou project China applied for first time construction material dams. This article further explores concept from conducting on-site direct shear tests research on ratios invents a new structure method by combining with rockfill. also proposes digital mixing intelligent dynamic control rock. The results show that content not exceeding 60% can produce compressive strength no less than 6 MPa. stress body is small does tensile stress. added has certain shear-bearing capacity, friction coefficient 0.99~1.10 MPa, cohesion 0.26~0.53 high residual strength, accounting 60~80% peak strength. At same time, problems large fluctuations moisture uneven grading riverbed mix during production process, significant influence safety caused dispersion gravel, are resolved, ensuring quality preparation. successful application achieved breakthrough key technologies regions, proving feasibility having broad prospects promotion.
