在植被混凝土护坡绿化技术的推广应用过程中,植被混凝土基材本身的力学性能的研究仍相对滞后,因此对植被混凝土力学性能进行研究是必要的。本文以植被混凝土为研究对象,对植被混凝土的构成、特点、使用材料、配比、制造方法等做了一个全面的介绍;并对高速公路边坡植被混凝土层通过力学理论和三维弹塑性有限元计算对其稳定性进行了分析,数值模拟的结果表明:在高值的雨水载荷作用下植被混凝土层未出现失稳破坏,此结果与经典力学理论分析相近。最后对植被混凝土的多功能化进行了探讨。
In the popularization and application of vegetation revetment greening technology, the mechanical properties of vegetation concrete substrate itself is still lagging behind, so it is necessary to study the mechanical properties of vegetation concrete. This paper takes vegetation concrete as the research object, and gives a comprehensive introduction to the constitution, characteristics, materials, proportioning and manufacturing methods of vegetation concrete. The vegetation layer of highway slope vegetation is analyzed by mechanics theory and three-dimensional elasto-plastic finite element The result of numerical simulation shows that under the effect of high rain load, the instability damage of the vegetation layer does not appear, which is similar to that of the classical mechanics theory. Finally, the multi-functionalization of vegetation concrete is discussed.
