This research aims to investigate the basic concept of load transfer mechanisms by focusing on physical model tests and theoretical analysis of the stress field. In order to perform a quantitative evaluation by stress analysis based on the Lame-Maxwell equations of equilibrium, theoretical solutions of stress distribution in sand heap, sand valley, earth retaining wall and slope were developed and verified by physical models. Finally, the use of the cylindrical air gypsum plaster on the slopes as a monitoring method of principal stress direction stress was examined by observing the direction of the crack.

本研究旨在探讨荷载传递机制的基本概念，着重于物理模型试验和应力场的理论分析。为了通过基于Lame-Maxwell平衡方程的应力分析进行定量评价，建立了沙堆、砂谷、挡土墙和边坡应力分布的理论解，并通过物理模型进行了验证。最后，通过观察裂缝的方向，验证了在边坡上使用圆柱形空气石膏抹灰作为主应力方向应力监测方法的可行性。
