Research on the Dynamic Response of Gravity Dam under Blasting Vibration

With the continuous development of blasting technology, it has been widely used in various construction projects. While bringing convenience to construction, it also has a series of negative effects on surrounding buildings (structures), especially the negative effects of blasting vibration on buildings (structures), which has been paid close attention by scholars at home and abroad. For blasting vibration on the dynamic response of the gravity dam to produce, this article adopts the method of numerical simulation, the finite element software ANSYS is applied, the numerical calculation model of concrete gravity dam is established and the dynamic time-history analysis is calculated, in the different blasting conditions, the blasting vibration on the dynamic response of gravity dam is obtained, the calculation and analysis results as basis is supplied for the selection of the blasting vibration monitoring part of the gravity dam.

Giluyskaya Hydropower – new approach to project development

Multivariate water-power calculations were carried out and the main parameters of the reservoired Gilyuyskaya HPP were justified. The Gilyuy river is located in the Amur Region of the Far Eastern Federal District and is a right tributary of the Zeya River. The mouth of the Gilyuy river is located above the power site of Zeyskaya HPP. Based on the water-power calculations, it was found that the most efficient way is to use live storage capacity of 3.13 km3 and the turbine flow rate of HPP equal to 268 m3/s. The installed power capacity of Giluyskaya HPP is justified on the basis of maximizing the net present value and is assumed to be 213 MW. Hydropower has three hydraulic units with radial-axial turbine RO115with impeller diameter of 3.35 m and synchronous speed of 214.3rpm.The high-head water power development includes as follows: a concrete gravity dam, a concrete spillway dam with nappe-shaped profile, a concrete power dam with three water inlets and three steel pipelines with a diameter of 4 m, as well as HPP building. The HPP building is 48.68 m long and consists of three hydropower units with a width of 16.23 m. The length of the tent of HPP building along the flowstream is 18.5 m. The assembly area is 24.34 m long.
