Key technologies for performance characterization and engineering application of high-performance materials in geotechnical transportation engineering

摘要

本文面向交通岩土工程中高性能材料推广应用需求，研究水泥改性再生基层、水泥稳定骨料基层、全天候填料及超高性能 混凝土桩的性能表征与工程应用关键技术。针对传统经验设计方法难以准确描述新型材料非线性、非均质行为的问题，构 建了“材料识别-试验评价-模型修正-现场验证-设计反馈”的技术体系。研究从回弹模量建模、湿态通行性评价、干燥行为 分析及波动测试判读等方面展开，提出适用于工程设计与质量控制的指标体系。分析表明，高性能材料可显著提升路基承 载、施工连续性和结构耐久性，但需同步完善试验方法、参数选取和现场验收标准。

Abstract

This paper studies key technologies for the characterization and engineering application of high-performance materials in geotechnical transportation engineering. Aiming at the limitations of conventional empirical design methods when applied to cement- modified recycled base, cement-stabilized aggregate base, all-weather fill, and ultra-high-performance concrete piles, a material evaluation framework integrating resilient modulus modeling, trafficability assessment, and wave-based integrity testing is proposed. The study discusses testing procedures, parameter interpretation, model correction, and field implementation paths. Results show that high-performance materials can improve bearing capacity, construction efficiency, and durability, while their nonlinear and heterogeneous behavior requires more refined design and verification methods.
