Recently, the Chengdu Municipal Science and Technology Bureau publicly announced the "List of Proposed Projects for the Fourth Batch of Key R&D Projects in Chengdu in 2024."

The research topic "Development and Application of New Composite Materials for Grouting Reinforcement of Red-Bed Fill Foundations," declared by the Chengdu Engineering Corporation Limited (CECL), has been approved for project initiation. Targeting the prominent issue of settlement and deformation of fill foundations in red-bed areas, and building on traditional foundation grouting reinforcement, the topic focuses on grouting materials and key technologies for foundation grouting construction through theoretical research, numerical calculation, laboratory tests, and field tests. Its research results can provide technical support for the construction of similar high-fill engineering projects.
