... Abstract The leakage problems in dam abutment of Tuokou Hydropower Station are first revealed by geological analysis. The complexity of the special geological conditions of the dam abutment is mainly due to the widely distributed large fractures and karst caves. It's hard to conduct grouting...

... Abstract: The coal mined out area in sandstone is an outstanding problem for Fukuoka arch Dam's abutment stability. To determine the concrete replacement depth of coal mined out area in abutment, this paper conducted numerical simulation by employing finite element method, and compared...

... of groundwater and for irrigation. This paper highlights the engineering geological characterization of the rock masses exposed at the dam abutments and foundation area at the proposed Kangir dam site. This site is located in western Iran in Elam province, and will impound flow from the Kangir River. The study...

... Abstract The response of flat square rock roofs is examined numerically using a three dimensional explicit finite difference code. Roofs are modeled as plates, loaded by their own weight, vertically cracked with persistent joints along their abutments and their diagonals. Numerical results...

... their trend change, surface sampling and measurement of the discontinuities has been done in both right and left abutments of the dam axis (Figure 1). Totally around 2500 discontinuities were surveyed out of which 1400 belong to the right abutment and 1200 are from the left abutment. In order to statistically...

... ABSTRACT Concrete dams which are constructed in narrow gorges on rock formations should be able to sustain the high pressure imposed from the water behind the dam. This pressure is transmitted to the rocks at the abutment and foundation through the concrete dam body. In double curvature...

..., serves as an example of the numerical simulation of the failure process and the capacity. The results illustrated in this paper from the numerical simulation are approximately consistent with that of physical tests. 1. INTRODUCTION The problem of stability for arch dam abutment is acquiring vital...
