Embodiment example

[0037] A pad pond permeable slope plate simulation micro-friction force test system of the present invention has been experimentally studied in the study of the stability of the pad pond permeable slope in Wudongde. In the case of a slope, the maximum instantaneous tensile force on the permeable slope slab is 712.2T. The test results obtained have been adopted by the design, and the slope anchorage design has been designed according to the test data, and it is currently in the field construction stage.

Abstract

A micro-friction stress test simulating system of a plunge pool water-permeable side slope plate comprises a limiting box and a side slope simulating plate arranged in the limiting box, wherein the periphery of the limiting box is connected with a plunge pool side slope, gaps are reserved in the periphery and the bottom surface of the side slope simulating plate, universal wheels for limiting are adopted for the gaps reserved in the periphery and the bottom surface, a tension-compression sensor perpendicular to the side slope simulating plate and the limiting box is arranged in the side slope simulating plate, and the side slope simulating plate is vertically provided with multiple water-permeable holes in a thorough mode. The micro-friction stress test simulating system is used for stress test simulation of the high-dam plunge pool water-permeable side slope plate, the influence on a boundary friction force is reduced to the greatest degree by arranging the universal wheels under the situation that water-permeable holes and the gaps are similar in water permeation, so that the water-permeable plate moves in the direction perpendicular to the plate surface, the stress process of the water-permeable plate in a plunge pool is obtained by utilizing the tension-compression sensor, the risk that discharged flood damages the plunge pool side slope is reduced, meanwhile a construction period is shortened, and the construction difficulty and construction costs are reduced.

Description

technical field [0001] The invention relates to the technical field of high dam flood discharge and energy dissipation pad pond side slope protection in water conservancy projects, in particular to a pad pond permeable slope plate simulation micro-friction stress testing system and method. Background technique [0002] Using pad ponds to dissipate energy is one of the main energy dissipation methods for high dam flood discharge. With the continuous deepening of hydropower development, the scale of high dam construction in my country is increasing day by day. World-class large-scale water conservancy projects with a level of 200m or even 300.0m have been built or are under construction, such as Wuqiangxi, Yantan, Three Gorges, Ertan, Xiaolangdi , Shuibuya, Nuozhadu, Xiaowan, Jinping, Goupitan, Xiluodu, Xiangjiaba, Wudongde, Baihetan, etc. However, most of my country's high dam projects are located in the western alpine and valley areas. The notable characteristics of its flood...
