宏观裂缝 meaning in English
macro crack
macrofissure
macrofracture
macroscopic cracking
macroscopic fracture
Examples
- Virtually , it is a process that the ac material gradually deteriorates and forms cracks under the traffic loads
其实质是沥青结构层在交通荷载循环作用下内部逐渐出现损伤劣化形成宏观裂缝的过程。 - The simulation result of performance of concrete was compared with that of the experiments . furthermore , the three - dimensional random aggregate model was established and the three - dimensional mesh of simple supported beam was generated automatically
混凝土的破坏，实际上是由于其内部的微裂缝的萌生、扩展、相互汇合，进而形成宏观裂缝贯穿混凝土而导致其失稳破坏的过程。 - So , it is important to analyze the developing law of the damages and the macro - damages in concrete , acquaint the stress field , displacement field and damage field in structure for preventing the destruction in concrete structure caused by damage and fracture
因此分析混凝土体内损伤及宏观裂缝开裂的发展规律，了解混凝土体内的应力场、位移场及损伤场，对于防止混凝土体出现损伤、断裂破坏有重要的借鉴作用。 - The steel - fibre reinforced concrete ( sfrc ) is a new kind of multiply - composite material , and the short steel fibres are distributed disorderly in the concrete . the main function of the short steel fibres is to hinder the expandance of inner microscopic and macroscopic cracks in the concrete . therefore , sfrc is used extensively in building highway and airport pavement . with the extensive applyment of sfrc , the experiment and research of it has been concerned and valued by the scholars of internal and overseas
钢纤维混凝土是在普通混凝土中掺入乱向分布的短钢纤维所形成的一种新型的多相复合材料，其中乱向分布的短钢纤维主要作用是阻碍混凝土内部微裂纹的扩展和阻滞宏观裂缝的发生和发展。因此，在修筑公路路面和机场道面中得到广泛的应用。随着钢纤维混凝土这种新型复合材料的广泛应用，对钢纤维混凝土的试验与研究也日益受到国内外学者的关注和重视。 - During the shaping process of the concrete structures or members , there will exist defects such as small crevices in the body or on the surface inevitably , that is to say , the existence of original damages is unavoidable . under the acting of the outside factor , the original damages will develop and the new damages will appear . when the accumulation of the damages reach a certain degree , the macro - damages will appear and new damages will also produce at the tip of these macro - damages
混凝土结构或构件在浇筑成形的过程中，混凝土体内或表面将不可避免的存在细微裂隙等缺陷，即混凝土体中不可避免的存在初始损伤，在外界因素作用下，损伤会有所发展并会出现新的损伤，当损伤积累到一定程度时，混凝土体中将会出现宏观裂缝，而宏观裂缝的端部又将发生新的损伤，再积累而引起裂缝的扩展，这种持续的扩展将对结构的稳定性产生极大的危害。
