Considering the moisture-proof factors affecting structural durability, there are four main moisture sources for light timber building, including rain water, condensed water, moisture content of material and foundation moisture. Concrete moisture-proof and waterproof technical engineering measures are adopted for structural systems, such as foundation, wall and roof of light timber structure, to provide excellent design methods for moisture-proof of timber building. These technical measures have significant meanings for improving the waterproof and moisture-proof performance of timber building and ensuring structural durability.%从影响结构耐久性的防潮角度出发,轻型木结构建筑潮湿的主要来源有降水、冷凝水、材料含水率和基础潮湿四点.通过对轻型木结构的基础、墙体和屋面等结构体系采取具体的防潮、防水工程技术措施,为木结构建筑防潮提供了优良的设计方法,对提高木结构建筑的防水和防潮性能,保持其结构耐久性具有重要意义.
