摘要
根据客运专线所处的施工环境及原材料的实际现状,结合高耐久性混凝土配合比设计和聚羧酸系外加剂的使用特点,对高速铁路客运专线灌注桩高性能混凝土施工中一些常见问题进行了分析并提出了解决的措施。
Based on the constructional environment and the present condition of raw materials for the engineering projects of passenger dedicated railway, and combining with the consideration on the special feature of proportion desoign of durabal HPC and the application of polycabonate admixture, some common problems about concreting the poured piles with HPC are discussed and the proposals and measures for solving them are put forward.
