Abstract:Under the strategic goal of "dual carbon", taking the application research of green forest solid waste in road solidified soil as the background, and through the experimental research and theoretical mechanism analysis, the intensity change law of green forest waste in solidified soil is revealed. The experimental results show that when the cement content is 5%, the strength loss of wood blocks after immersion in water is great, and it is not conducive to the compaction process. When the cement content reaches more than 10%, the wood block has a certain strengthening effect in the solidified soil, and the cement gelling products can form a network reinforced structure. When the cement content is 15%, the strength of solidified soil increases with the increase of wood block content. When the wood block content is 40%, the strength reaches 1.8 MPa.
