摘要

在不同温度水平下开展饱水马尾松（

Pinus massoniana

）同一生长轮内早材与晚材拉伸蠕变行为的对比研究，在生长轮尺度上揭示饱水木材的拉伸蠕变特性，并运用Burger模型对饱水早材与晚材的拉伸蠕变特性进行模拟预测。结果表明：任一温度水平下，无论沿轴向还是弦向拉伸时，饱水早材比晚材更易发生瞬时弹性变形与黏弹变形；在30~80 ℃温度范围内，饱水早材与晚材的瞬时弹性变形受温度影响不显著，黏弹变形随温度的升高而增大，且晚材的黏弹变形对温度变化较为敏感，拉伸蠕变初始阶段所需时间较短。Burger模型可以模拟饱水早材与晚材沿轴向与弦向的拉伸蠕变过程，拟合的决定系数（

）大于0.956。

Abstract

A comparative study on the tensile creep behavior of earlywood (EW) and latewood (LW) obtained from the same growth ring of Masson pine (

Pinus massoniana

) was carried out at different temperature levels of hydrothermal treatment

to reveal the characteristics of the tensile creep behavior of water-saturated wood at the growth ring level. The tensile creep characteristics were then simulated using the Burger model for prediction. The results showed that EW was more prone to generate instantaneous elastic deformation and viscoelastic deformation than LW at each temperature level

regardless of tangential or longitudinal tension. The temperature ranging from 30 ℃ to 80 ℃ had no significant effect on the instantaneous elastic deformation of both EW and LW from Masson pine while the viscoelastic deformation and the plastic deformation heightened with the increasing temperature. The viscoelastic deformation of LW was more sensitive to temperature change than that of EW. The time required for the initial creep stage in LW was shorter than that in EW. The Burger model was approved to simulate the creep characteristic of water-saturated EW and LW under tangential and longitudinal tension

with a coefficien

t of determination (

) of greater than 0.956.
