房屋建筑、设备基础等的板式桩承台的厚度主要由其抗冲切强度控制,由于冲切破坏属于脆性破坏,因此,设计时板的厚度取值较大。盐城工学院建工系荀勇等提出了钢纤维混凝土桩承台的试验研究,结果表明:钢纤维掺入混凝土后,不仅提高了材料的抗拉强度,而且大幅度提高了材料的韧性。当 The thickness of slab pile foundations such as house construction and equipment foundations is mainly controlled by its punching shear strength. Since the punching damage is brittle, the thickness of the slab is designed to be large. Yan Yong Institute of Construction Engineering Department Yong Yong put forward the experimental study of steel fiber reinforced concrete pile caps, the results show that: steel fiber mixed with concrete, not only improves the material’s tensile strength, but also greatly improved the toughness of the material. when
