This study explored the use of root cross-section dimensions, root distribution, uplifted root/soil volume, greenwood modulus of rupture and soil/greenwood densities in a biomechanical close form model based on past literature to estimate the resistance to uprooting of tree root–soil plates. This study used data obtained from a tree-pulling exercise involving 20 planted Samanea saman, a common species of planted wayside trees in Singapore. The trees were individually pulled to failure by uprooting. The failure load, root cross-section dimensions and uplifted root/soil volumes of each individual pulled tree were recorded. The results calculated using the hypothesised close form model showed a good match with data from the tree-pulling exercise. This close form model provides a better understanding of the stability of shallow-rooted trees with root–soil plates.

树根-土壤板的锚固和稳定性

这项研究探索了根系横截面尺寸，根系分布，根系/土壤体积增加，绿林破裂模量和土壤/绿林密度的使用，该模型基于过去的文献来估计树木对根部的抗连根性–土板。这项研究使用了从20棵种植的Samanea saman进行的拉树练习中获得的数据，是新加坡种植的路边树木的常见物种。树木因连根拔起而被单独破坏。记录每棵被拉树的破坏载荷，根部横截面尺寸和根部/土壤的抬升量。使用假设的封闭形式模型计算的结果表明，该结果与拔树活动的数据非常吻合。这种紧密形式的模型可以更好地理解带有根-土板的浅根树木的稳定性。
