摘 要
随着土木工程建设的不断发展，结构裂缝问题逐渐成为影响工程质量和耐久性的关键因素之一。裂缝不仅影响结构的外观美观，还可能降低结构的承载能力，甚至对人们的生命财产安全构成威胁。因此，深入研究土木工程结构裂缝的成因及预防措施，对于提高工程质量和保障结构安全具有重要意义。当前，国内外学者对土木工程结构裂缝的研究已取得一定成果，但仍然存在一些问题和挑战。本研究针对土木工程结构裂缝问题，深入分析了裂缝的成因，并提出了相应的预防措施。通过对设计与施工因素、材料性能与选择、温度与湿度变化、地质条件与地基处理以及荷载作用与结构性能等多个方面的综合分析，本研究揭示了土木工程结构裂缝的主要成因。同时，结合工程实践，本研究提出了一系列有效的预防措施，包括加强设计与施工过程的质量控制、选用高性能材料与优化材料配比、强化温度与湿度变化下的结构保护、精准评估地质条件与科学处理地基以及合理设计荷载与加强结构性能评估等。本研究成果不仅有助于提高土木工程结构的质量和耐久性，而且为工程实践提供了重要的理论支持和技术指导。

Abstract
With the continuous development of civil engineering construction, the structural crack problem has gradually become one of the key factors affecting the engineering quality and durability. Cracks not only affect the appearance of the structure, but also may reduce the carrying capacity of the structure, and even pose a threat to the safety of people's life and property. Therefore, it is of great significance to deeply study the causes and preventive measures of civil engineering structure cracks to improve the engineering quality and guarantee the structural safety. At present, domestic and foreign scholars have made some achievements in the research of civil engineering structure cracks, but there are still some problems and challenges. This study analyzes the causes of cracks and puts forward corresponding preventive measures. Through the comprehensive analysis of design and construction factors, material performance and selection, temperature and humidity changes, geological conditions and foundation treatment, load action and structural performance, this study reveals the main causes of cracks in civil engineering structure. At the same time, combined with the engineering practice, this study puts forward a series of effective preventive measures, including strengthening the quality control of design and construction process, choose high performance materials and optimize material ratio, strengthen the structure of temperature and humidity change protection, accurate assessment of geological conditions and scientific treatment of foundation and reasonable design load and strengthen the structure performance evaluation, etc. The present research results can not only help to improve the quality and durability of civil engineering structures, but also provide important theoretical support and technical guidance for engineering practice.
