Abstract

Rockfall protection soil embankments are structures that can effectively reduce rockfall hazards along roads. They are economical and easy to construct and maintain by using locally available soil. However, a performance design method for rockfall protection soil embankments has not yet been established, and is the goal of this study. In the present study, static loading tests were conducted using two different weight shapes to clarify the influence of the weight shape on the deformation behavior of soil embankments. Based on these tests, the punching shear failure mechanism of the soil embankments was investigated. The influence of the model scale (the scale effect) on the deformation failure behavior of the soil embankments was clarified through static loading tests on reduced models at three different scales. From these model experiments, the surface deformation, internal deformation, and load–penetration relationships of the soil embankments were summarized. The results indicated that the spherical weight damaged a wider area than the polyhedral weight, and the maximum and ultimate loads exhibited a constant relationship with the deformation of the soil embankment extension between the model scales.

静力荷载作用下防落石土路堤变形、阻力特性及尺度效应

防落石土路堤是一种能有效减少道路沿线落石灾害的结构。它们经济且易于使用当地可用的土壤来建造和维护。然而，目前还没有建立起防落土路堤的性能设计方法，这也是本研究的目标。本研究采用两种不同重量形状进行静载试验，以阐明重量形状对土路堤变形行为的影响。在此基础上，对土路堤冲剪破坏机理进行了研究。通过对三种不同尺度的模型进行静载试验，阐明了模型尺度（尺度效应）对土路堤变形破坏行为的影响。通过这些模型试验，总结了土路堤的表面变形、内部变形和荷载-侵彻关系。结果表明，球形荷载比多面体荷载的破坏面积更大，最大和极限荷载与模型尺度之间的土路堤延伸变形呈恒定关系。

期刊介绍： Soils and Foundations is one of the leading journals in the field of soil mechanics and geotechnical engineering. It is the official journal of the Japanese Geotechnical Society (JGS)., The journal publishes a variety of original research paper, technical reports, technical notes, as well as the state-of-the-art reports upon invitation by the Editor, in the fields of soil and rock mechanics, geotechnical engineering, and environmental geotechnics. Since the publication of Volume 1, No.1 issue in June 1960, Soils and Foundations will celebrate the 60th anniversary in the year of 2020. Soils and Foundations welcomes theoretical as well as practical work associated with the aforementioned field(s). Case studies that describe the original and interdisciplinary work applicable to geotechnical engineering are particularly encouraged. Discussions to each of the published articles are also welcomed in order to provide an avenue in which opinions of peers may be fed back or exchanged. In providing latest expertise on a specific topic, one issue out of six per year on average was allocated to include selected papers from the International Symposia which were held in Japan as well as overseas.
