摘要
冰雹是最严重的灾害性天气现象之一,且其灾致损失呈现逐年递增趋势,如何减少冰雹灾害造成的损失成为工程领域必须面对的现实问题.然而目前结构抗冰雹冲击研究十分有限,因此系统开展结构冰雹冲击减灾防灾理论和实践研究具有重要意义.本文首先综述了冰雹力学性能,然后详细介绍了工程结构抗冰雹试验和数值模拟研究现状,最后对冰雹和强风、暴雨耦合作用及机理相关研究进行了展望,以期为结构抗冰雹冲击研究提供基础资料和新的视角.
Hail is one of the most serious disastrous weather phenomena,and the loss caused by hail is increasing year by year.How to reduce the hail-induced loss has become a practical problem that must be faced in the engineering field.However,the research on the hail impact resistance of structures is very limited at present.Therefore,it is of great significance to systematically investigate the theory and practice of structural hail impact disaster reduction and prevention.In this study,the mechanical properties of the hail are first summarized.Then,the experimental and numerical research status of hail resistance of engineering structures is introduced in detail.Finally,the research on the coupling effect of hail,strong wind and heavy rain and its mechanism are prospected.This study is supposed to provide the basic data and new perspectives for the research on hail resistance of structures.
