Behavior of angle cut cylinder excavation by cut reinforced earth work method
When a structure such as a bridge pier is constructed in a mountainous district full of steep slopes, earth cutting or earth retaining by soldier pile method is commonly used. However, cutting on a steep slope will produce a large-scale cut slope, and will cause a substantial modification of natural environment, raising problems in the treatment of surplus soil in construction and increase in the management area. Furthermore, the soldier pile method requires long piles to be driven in a steep slope; this takes a wide construction yard. Further, this work requires a concurrent use of round anchors, which results in a longer construction period and greater construction costs. Under these circumstances, the authors of this paper propose the earth retaining method (angle cut cylinder earth retaining method) mainly based on the cut reinforced earth method, and clarify the behaviors of the ground and structures by measurement. At the same time, they are currently investigating the designing method. This method ensures a high degree of stability without tipping earth pressure balance very much, and minimizes modification of the natural environment. This paper reports the deformation characteristics of angle cut cylinder excavation form based on the 3D plasticity analysis, and the behaviors of ground and structures obtained from the result of measurement in field tests.
