工程结构在施工和使用过程中产生的裂缝不仅影响其功能和安全,而且需要大量投入进行修补和防护。通过对各种工程结构裂缝的形式、分布特征及规律的调查研究,结合对工程结构的力学性质和环境特征的分析,从深层次探寻裂缝产生的原因,建立裂缝成因同其表现形式之间的紧密联系。在对裂缝成因有足够认识的基础上,提出针对各类工程结构裂缝有效防护与修补的思路,以提高结构的耐久性与可靠性,延长其使用寿命。最后,依据对研究结果的整理,开发建立了包含“各类结构裂缝成因-表现形式-治理措施”等主要功能的强大数据库,以便在工程上对裂缝进行快速查询和判断,从而提出有效防治措施。
Cracks in the construction and use of the project structure not only affect its function and safety, but also require substantial investment in repairs and protection. Through the investigation and research on the forms, distribution characteristics and regularities of all kinds of engineering structure cracks and the analysis of the mechanical properties and environmental features of the engineering structure, the paper explores the causes of the cracks from a deep level and establishes the relationship between the causes of cracks and their manifestations Closely linked. On the basis of sufficient understanding of the causes of cracks, this paper puts forward the idea of effective protection and repair for all kinds of engineering structures in order to improve the durability and reliability of structures and prolong their service life. Finally, based on the research results, a powerful database including the main functions of “causes of various types of structural cracks - forms of manifestation - governance measures” was developed and developed so as to make quick inquiries and judgments on cracks in engineering so as to put forward effective Prevention.
