摘　　要：对正交胶合木(CLT)销槽承压性能研究进行了系统回顾。归纳总结了木材销槽承压性能测试标准,分析比较了不同测试方法的优缺点,梳理了销槽承压性能影响因子,并对现有CLT销槽承压性能计算公式进行整理。研究表明:CLT销槽承压性能与木材销槽承压性能有较大区别,除木材销槽承压的影响因素外,层板材料和组坯结构、销类连接件打入和加载方向、横向层厚度占比等对CLT销槽承压性能也有很大影响。建议针对主要因素进行深入研究,建立统一的CLT销槽承压性能理论预测公式,并对采用国内材种研发的CLT销槽承压性能展开系统研究。The latest research progress on embedment test was systematically summarized in this paper.The advantages and disadvantages of different test methods were analyzed by comparing the existing test standards.The impact factors and formula calculations were sorted out.Research showed that embedment properties of CLT was quite different from that of wood.In addition to the impact factors of the wood embedment test,the layer material,layup configuration,dowel location,loading direction and the thickness ratio of transverse layer to the total thickness also had significant influence on CLT embedment properties.It was recommended to make in-depth research on the main factors,to establish a unified theoretical prediction formula and to develop CLT research and application on the domestic wood species in China.
